If you just started playing for the day in this video, you are definitely 4.5 if all cylinders in the right temperature. A 4.0 player don't usually hit with loads of power in its initial rally. That is with assumption that you can still hit with that energy even after 2 set play on court!!!! Longevity in powerstrokes requires softer grip, which I think you are using into your strokes.
This is my kind of analysis when scouting.
