Pedro06 Posted January 19, 2008 Share Posted January 19, 2008 Hello, i don't understand how calculated the rating grippers. This morning I made a calibrated (like the same of dave morton), I tried on the HG100 and I had to hang 22.5kgs so that it closes, what's the rating of this hg100? I ask this for the grip of iron contest that I organize. Thank. Quote Link to comment Share on other sites More sharing options...
Cannon Posted January 20, 2008 Share Posted January 20, 2008 There's probably an easier way to do this, but here's how I get the calibration. First, you need to know that 150lbs was picked as the standard for a 3.0 rating. So the formula would be: [(Your Calibration)/150]*3 Or in this case, assuming 22.5kg is 49.6lbs: (49.6/150)*3 = 0.99 rating. I hope that's right because that's how I've been doing it Quote Link to comment Share on other sites More sharing options...

I hope that's right because that's how I've been doing it That seems REALLY high for a HG100, mines WAY easier than my Trainer, a little harder than a sporting goods store gripper. But that could be because mine's pretty seasoned. Quote Link to comment Share on other sites More sharing options...
foxyj75 Posted January 20, 2008 Share Posted January 20, 2008 That's 150 lbs. for the HG 100 right? If so, WOW!!!! Mine's about like Derek's is; slightly harder than a common sporting good store plastic jobber. Maybe the wrong handle markings on it??

Mine's about like Derek's is; slightly harder than a common sporting good store plastic jobber. Maybe the wrong handle markings on it?? The 150 is for the average #3. it doesn't have the wrong handle markings on it, either this guys has a REALLY hard HG100, he's caling them wrong, or Matt's calculations are wrong. No offense to anyone, just stating the possibilities. Pedro, just to be sure, are you 100% positive your cal setup is the same as the RGC? Oh and to Pedro, you really don't need to cal grippers under a #3, it's completely unnecessary since that small of grippers doesn't count for records or anything.

I knew the 150 was for an average #3, but I just wanted to be sure it was the lbs. the HG100 supposedly cal'ed at. Still, WOW!! I knew the HG's varied alot, but thats ridiculous!!! BTW, Derek, do you have a HG350? If so, does it feel like a brick wall? Just curious!!! Later :D Quote Link to comment Share on other sites More sharing options...
acorn Posted January 20, 2008 Share Posted January 20, 2008 I dont think there is anyway to determine with any sureness a rating for a gripper that light. the main reason for that is the ratios are based on the difference between a (average) #3, and (#average) #4 based on bulk testing. there is no known basis for an (average) #2, #1, or Trainer to create ratios from and I doubt the average constant that was determined for the #3-#4 of 59# would hold up exactly much below a #3. IMHO anything below about a #2.7 would be a guess. Anything below a #2 would be a random guess if you try to base it on the #3-#4 ratios. As a result I think the calibration method used by Greg & Dave's RGC is only accurate from just under a #3 to a #4 unless some standard calibration for a #2, #1, and #T is derived. - Aaron Quote Link to comment Share on other sites More sharing options...

Or did you know that and I'm just really confused? Hahaha Yeah I ahve one and it feels like a brick wall but as Aaron will testify, it's not as hard as it feels. The HGs have a PSYCHOTIC sweep but don't load up. The sweep on mine feels like a 3.5, but Aaron tried it and the crush was only about a 3.0.

dima700 Posted January 20, 2008 Share Posted January 20, 2008 I once had an HG 150 that was as hard as my #4 Later I found out the spring was stuck and wouldn't move Quote Link to comment Share on other sites More sharing options...
GetAGrip87 Posted January 20, 2008 Share Posted January 20, 2008 Guys, there is no way in hell his HG100 calibrates to 150lbs There's probably an easier way to do this, but here's how I get the calibration. First, you need to know that 150lbs was picked as the standard for a 3.0 rating. So the formula would be:[(Your Calibration)/150]*3 Or in this case, assuming 22.5kg is 49.6lbs: (49.6/150)*3 = 0.99 rating. DO NOT multiply by 3. 49.6/150= 0.33 I hope that's right because that's how I've been doing it I'm not sure how to calibrate a gripper below a #3 and it doesn't really matter but... I guess an HG100 would be about a 0.33. Sounds about right. Quote Link to comment Share on other sites More sharing options...

I guess an HG100 would be about a 0.33. Sounds about right. No Scott I think he did it right. That means it cals at a .99 on a CoC scale, not that it cals at 150 lbs. You can just use ratios for CoC rankings. If you know and average #3 is 150 lbs then you use simple ratios. 150/3 = 49.6/X where X equals the CoC number ranking. When you cross multiply and solve out it equals .99 Quote Link to comment Share on other sites More sharing options...
GetAGrip87 Posted January 20, 2008 Share Posted January 20, 2008 Whatever, no HG100 is going to be a #1. Quote Link to comment Share on other sites More sharing options...
vikingsrule92 Posted January 20, 2008 Share Posted January 20, 2008 (edited) Whatever, no HG100 is going to be a #1. I think so too, but the ratios I did (I'm pretty sure) is a correct the way to find out CoC rank. Maybe he cal'd it wrong I don't know. Actually, now I'm not sure. Maybe I did do it wrong because it doesn't work for the average #4 number (209 right?). But in theory those ratios should work, maybe not though.

vikingsrule92 Posted January 20, 2008 Share Posted January 20, 2008 I think I may have it figured out if you use the existing ratio of 209/150 of 4/3. That would mean an average #2 is ~107.6 and the average #1 is ~77.3 so this gripper would be a .642, dividing 49.6/77.3. However this very well could be wrong and I'm a complete idiot Quote Link to comment Share on other sites More sharing options...
neilkaz Posted January 20, 2008 Share Posted January 20, 2008 Every HG100 that I've ever seen or tested is inbetween the IM Sport and Trainer and usually closer to the Sport. Quote Link to comment Share on other sites More sharing options...
Pedro06 Posted January 20, 2008 Author Share Posted January 20, 2008 I want to know every gripper calibrated because at the contest grip of iron there are some beginner's who cant't close more of the HG100 or hg150. Thus how I shall make the classification of the gripper's event? Quote Link to comment Share on other sites More sharing options...
Pedro06 Posted January 20, 2008 Author Share Posted January 20, 2008 result of this morning (2 tries with every gripper to verify) HG100 = 19.5kgs // 43lbs HG150 = 31.25kgs // 69lbs Coc 1 = 32.5kgs // 71.5lbs HG200 = 37.5kgs // 82.5lbs I think that figure are just because I found that was #1 equal in HG150 and HG200 really more hard. I use this for made the calibrated and for rating i don't understand!!!!! RGC Quote Link to comment Share on other sites More sharing options...
Teemu I Posted January 20, 2008 Share Posted January 20, 2008 The rating for that HG 100 should be under 0,30. This is how the ratings should really be calculated, this was told to me by Greg Amidon: Average Difference Guide 32 T-G 13 Sport 45 T-S 14 T 59 #1 - T 24 1 83 #2 - #1 27 2 110 #3 - #2 40 3 150 #4 - #3 59 4 209 Take the poundage you get from the calibrator, find what it is greater than or equal to, subtract it from the average value it is greater than or equal to, then divide that by the difference to the next gripper up, and add the gripper value to it. Anything higher than a 3 you use the 3 values. Trainer and below you add 0 as the gripper value at the end. Example: 180 pounds It is greater than a 3 average of 150. Subtract your reading from the avearage 3 value. 180-150 = 30 Divide the result from the difference of a average 4 to a average 3 30/59 = .508 Add the gripper value of the line you used for the calculations in this case a 3 3.508 I hope this helped to clear the confusion.

Pedro06 Posted January 20, 2008 Author Share Posted January 20, 2008 (edited) Ok Temmu thank you, now I understand. I have just finish, the result: I will use for the contest "grip of iron" , If you have remarks or things to be modified I am opened. HG100: 0.37 HG150: 0.87 Hold COC1: 0.92 New COC1: 1 HG200: 1.37 Hold COC2: 1.62 New COC2: 2.05 HG250: 2.12 COC2.5: 2.45 HG300: 2.8 COC3: 2.98 HG350: 3.36 COC3.5: 3.50 COC4: 4.01 Edited January 20, 2008 by Pedro06 Quote Link to comment Share on other sites More sharing options...
Teemu I Posted January 20, 2008 Share Posted January 20, 2008 It would help to see if you have come up with the right ratings if you posted the kilos and pounds as well. I could compare that to the data I have. Quote Link to comment Share on other sites More sharing options...
Pedro06 Posted January 20, 2008 Author Share Posted January 20, 2008 OK : HG100: 43lbs (not sur for the rating calcul) HG150: 56lbs (not sur for the rating cacul) #1: 83lbs HG200: 93lbs #2: 112lbs HG250: 115lbs #2.5: 128lbs HG300: 142lbs #3: 149lbs HG350: 171lbs #3.5: 180lbs #4 : 211lbs Quote Link to comment Share on other sites More sharing options...
Teemu I Posted January 20, 2008 Share Posted January 20, 2008 Your numbers looked fine to me. I also can't be 100 % sure of the two easiest, but now they can't be that far off. Everything from #1 and up look right. Quote Link to comment Share on other sites More sharing options...
