RGC Ratings Tips

[AdriaanRobert96]

So I just got myself an RGC Device from Arm Assassin Strength and I’d appreciate any advice or small tips and tricks I should think of when rating to get the beat rating possible..

Also how many times to rate a gripper before establishing a RGC.. etc etc.. 

Appreciate you!

Not a process, but some tips:

1) Start with a clean and oiled spring to hope for a repeatable rating. 

2) Know what your weights weigh. You cannot assume a 45 plate is 45 pounds. 

3) You cannot have anything invested in the result. Accept the number and try to replicate and verify that result. 

4) Put at least 30 reps on a new gripper. If the gripper will lose any spread, that usually happens on the first rep, but work it through about 30 with oil to make sure you are in a stable place. 

5) The most common mistake with false high ratings is a subjective opinion of when the gripper is closed. Ideally you want handles that are effectively touching but not adding any extra weight. The moment the handles actually touch it is possible for the rating to spike with no observable change to let you know you’re pinning the handles together. This is probably one of the hardest parts that takes experience. It’s hard to get a false low result because you can just see that the gripper is not shut.  

6) Don’t deal in decimals. 

7) Retest your results before publishing. If you get predictable results most of the time, and have an errant odd result then you cannot trust any of your results. Check your process until you understand the odd result. By odd I mean maybe you rated a gripper at 150 and next time it was 154. If you can’t identify in your process why that happened then you cannot trust any results. 

8] Understand that a rating is one piece of information. Pounds at the close. That’s it. There are many other elements to how a gripper feels to close. 

If I think of more I will add them.
