Default Strange PPI Results

This is on 2004 GT3 with 45K miles and 0 range 2 Over revs which would indicate missed shift. It is 2 owner car, and owned by the current owner since 2008 (about 17K miles), and has been primarily a track car, and in a very desirable condition with fresh suspension, and many services up to date. I am not willing to walk away from the car yet, but the fact that one entire side seems to show "something" is very strange.

All cylinders have very minor scoring.
Compression test: Cyl. 1 = 151 , 2 = 150 , 3 = 150, 4 =
145 , 5 = 145 , 6 =146 .
Leakdown test: Cyl. 1 = 4% , 2 = 5% , 3 = 5% , 4 = 19%
, 5 = 20% , 6 = 19%.
Check cam shaft deviation via tester. Bank 1 at -1.3.
Bank 2 at -3.73.

Additional usual checks to check for leaking valves and rings have shown no evidence of leak from either side.

I have asked for hot leak down and waiting to hear.

Any thoughts, ideas, or speculations?
