Solid points but HGs can and do vary massively. Matt says he has a Hg300 rating 115lbs. Also remember the sample size of on the heavy grips data is small. Like only 17 250s tested and 14 300s. 

So to me the only one thats seems a bit low is the Hg 250 but like we said on IG that could of been a mistake since it rated exactly the same as your coc 2 or it could just be a conincidence that its the same. 

Yeah I'm just taking them with a pinch of salt. What I don't want to do is spend a lot on filling the gaps to then find out that because they rate differently to what cpw do then I end up with another expensive gripper "the same" as what I already have even tho the numbers differ on the tags. That's my biggest concern tbh.

Yeah see where your coming from but ive spoke to  few people who have had ratings from Gog and not seen anything that would suggest they are wrong. Also the post about being on par with CPWs ratings on reddit. I think heavy grips are the hardest grippers to compare to other brands as well since the poundage and spreads vary so much. 

I bet if you tested say 50 of each strength gripper you would find a lot of variance. Also i remember a post on here by CPW saying that the average spread of a Hg was 65mm new but after some full closes and testing the ratings they lost about 5mm on average in spread. Maybe Matt can chime in a bit more on this?

All good my man, if they're accurate or comparable to cpw that's all I care about. If they happen to be light then whatever, gives me reason to buy more haha. Also means I've got one in that 130 Goldilocks zone so that's decent.

All of mine are 58-62mm (minus the 72mm 150) so if they're around 65mm~ when new then them losing 5mm from initial seasoning sounds about right. Unfortunately, I never even thought to check them when brand new but I guess Matt can confirm that from unpackaging and rating new ones.

There are two things that I hope to redirect here. This is general information; it's just your comment reminded me to post both these things:   

1) As a result of the comment above highlighting the number of grippers rated--and a report from a customer that their low HG250 was not reflected in our data--we discovered an error in our spreadsheet that was causing it to miss all HGs we've rated since about 2015! We really should have noticed the data was not changing update after update.  Here are all the figures.   

Capture.PNG

 

2) The second thing is what I would call an urban legend at this point. Heavy Grips do not vary "massively" compared to other brands. If you look at a gripper like the GHP 7 you can see it ranges from 138 to 160 representing a 22 lbs spread. HG300 is performing the same. But it can be said with 263 GHP 7s rated, there are many more chances for one to be high or low. So then compare similar sample sizes as another example, we have only rated 56 Trainers and there is a 12 lbs spread between low and high. Similarly we have rated 51 HG250s with only a 15 lbs spread. This is too similar to call them anything except "equally variable". On the contrary, we have only rated 52 Grip Genie Level 5s and there is already a 37 lbs gap. But honestly we don't hear people saying Grip Genie varies a lot, never mind that Grip Genie 5 has actually been critical to hitting some hard-to-find numbers.   

CPW has worked hard to change the messaging around variation. It is GOOD. Variation is the lifeblood of assembling a useful training set. People want options. We know people want the variations because when we post pre-rated grippers it's the edges that sell immediately. The ones that land around "average" absolutely take longer to sell.

As with most things in life, diversity is desirable. :)

Maybe just another point here that the Ratings Data might not tell the full story about this either. Truthfully we had ONE Grip Genie 5 at 126 and then I think the next lowest is something like 138. So there is a 37 lbs gap but largely due to one oddball gripper. Throw that oddball out and you have a more typical 25 lbs spread.

In a recent article on our blog, we posted a line graph that showed the curve of all our rated #3s. It was a nice Matterhorn-looking mountain. Meaning, a vast majority of the numbers are located in a sharp peak through the middle with foothills on either side. You can see that a bulk of all numbers are actually contained between roughly 145 and 154, a much tighter range.

The point I'm trying to make about Heavy Grips (or any gripper) is that the line graph is going to look the same. They all vary, and all have the same spike near the average falling off to both sides. If you want to know the rating of any one gripper, you need to rate that gripper.

I am the proud owner of this grip genie 5 with RGC 126, I closed it CCS yesterday (my record after 7 months of grip training). Really incredible it looks like a very hard heavy grip 250 and certainly not a gripper that could potentially be harder than a coc 3 ... I'm still mad at not being able to buy the 136.😟

Matt that was an awesome informative consise post. Now the chart has been updated HGs seem about the same as cocs in variation and with a large amount of tested grippers that is great. Are you updated the chart to include the crazy low 160 coc 3.5? 

Your 115lb 300 must be an oddball gripper. The crazy world of Gripper ratings.

Matt, great and interesting post. The data definitely looks better. However, there still seems to be some missing data? If you look back a few pages (page 35) someone had an 80lb rated HG200 but your minimum there is only showing 85? Unless it was left out for a specific reason?

Yeah the 3.5 will be in there eventually. We update in batches. 

My HG300 is old. The ratings data is only new grippers rated for CPW. I think my HGs are from about 2006 and CPW started in 2012. 😁

Was it Rate and Return?  The ratings data is only NEW grippers sold by CPW.

Edit: It was used. Used grippers and filed grippers are also not in the general data.

Very intelligent, in fact you never know what happened to a second hand gripper so its rating is only valid for its buyer and not to obtain reliable and objective data on a gripper model. Anyway with use and time the RGC probably changes a bit.🙂

Ah yes, looks to be second hand 👍. Fair enough, I guess you can't be too sure on what someone has or hasn't done to them whilst being in their possession.

Are you planning on prerating any more GGs?

That is actually a very good range for chest crushing. If you're strong at steel bending anything less would be too easy.

I wish there were more grippers in that range.

Well if you move it only 5mm. People who could fully close it chest crusing must be pretty strong. Its over double my coc 3. Crazy heavy gripper.

Yeah its a monster, the spring on it is insane. My world class feels harder, but that'st just because there's no "give" when you squeeze
