Yes, I did. The paper describes the computerized version of the Pierce
stretch method I use for testing F1B motors, the graph I posted
yesterday is a summary of those results. Computerization provides two
benefits, first of all it makes it possible to stress motors to the same
level of stress (as energy release depends on the maximum stress) and
this way make the results most comparable. Also it takes plenty of
samples, so that it minimizes estimation errors due to sampling.
