Compression test for 458 spider; 19.900 miles (32K km): see image

Any comments?

How I see this:

CIlinder 1: 10 bar = 145,04 PSI
Cilinder 2: 9,75 bar = 141,41 PSI
Cilinder 3: 10 bar = 145,04 PSI
Cilinder 4: 10,1 bar = 146,49 PSI
Cilinder 5: 9,75 bar = 141,41 PSI
Cilinder 6: 10,1 bar = 146,49 PSI
Cilinder 7: 9,9 bar = 143,59 PSI
Cilinder 8: 10,25 bar = 148,66 PSI

1. curve of cilinder is less slope
2. variation is around 5%
3. Shouldn't all cilinders be more like 13 bar?
4. other comments?
