As well, in my first post I was thinking of the A, N and C strips as ounces, pounds and tons. I asked why if at 4A we could set the upper limit at 7A due to the “or .003” whichever is greater” could we not set the upper limit of a 12N intensity at 21N? This would be direct scaling but instead when using N strips at 12N we only get to set the upper limit at 16N.

There is something incorrect in the logic. I could get behind the intensity only being able to increase 30% across all scales as ultimately these arc heights are trying to control residual stress characteristics of the components they peen. This “or .003 whichever is greater” does not make sense. Why at the lower end of the A scale would you allow the strip arc height maximum to grow larger than 30%? In fact at 4A the arc height % increase calculates to 75% if .003 is used. On the N scale the application of the “or .003 whichever is greater”, intensity of 1N is allowed to expand to 300% as a %arc height increase.
