Guys, and gals...
Everyone seems to be mis-interpreting the TW University tools... and I believe TW has gotten a few things wrong as well.
In the TW U. Power Potential thingie, the reports for each frame are depicted in terms of PERCENTAGES, not absolute relative values.
Power Potential: At each location the ball will rebound off the racquet at the indicated percentage of its impact speed.
This is a crap measure as they aren't measuring apples to apples. There is no physical way that you can compare power between say a PDR and a K90 and come out with anything meaningful using the measures TW is using.
The only use for their tool is isolation and identification of the sweet spot of a single particular frame.
