Hi, just wanted to provide some feedback. I used your excel file to compare 2 of my racquets (same racquets actually, just different setups).
Old specs were roughly 350 grams, 32 cm, 340ish sw
New specs are roughly 335 grams, 32.9-ish cm (33 is a close aproximation), 340ish sw.
The result of the plot seems to be quite well matched with my experience...the curves are similar in shape, and converge towards the "around wrist" value.
I take it that means that on short swings there's not much difference but on longer swings the difference grows.
If my understanding is correct, that matches pretty well with my subjective experience of the differences...there's not much difference in maneuverability on volleys, but I feel the new spec more snappy on serves and forehands...and as a result it tires me out slightly less late in the 3rd set.
