You really need to go to more comps and close more rated grippers with different numbers then. At comps in the past and then at Nationals this year (and several of us since then) have had (and are cu

The future of gripper rating is going to mean a graph of gripper strength done every mm etc to create a graph showing force needed throughout the close from start to finish. I have no idea what it wi

Good idea Joe. I've also dreamed up many other ways to streamline the process, or take weights out of the equation, etc. Thank you for experimenting with this. I'm saving my money for a computerize

If we had a graph (plotting lb force vs. '% close') showing three grippers:

1. a gripper with RGC of 180lb but with an easy sweep

2. An 'ideal' gripper with a straight line force / % close graph, also RGC of 180lb

3. A gripper with a hard sweep, but RGC of 180lb

Then the easy sweep would deviate from ideal, showing a plot under the 'ideal, the hard with deviation above ideal (except, of course at start & finish where all three examples would be the same: zero lb at 0% close and 180lb at 100% close).

So what I am suggesting is that a measure giving 'Hard' or 'Easy' compared to ideal would be obtained by comparing the area beneath the plot and expressing this as a percentage of 'ideal' so 'easy' would have an area less than that of the ideal, 'hard' obviously would be greater than 100% of 'ideal'.
