compression and leakdown numbers

Gentlemen (and Ladies),

Please excuse the cross-posting across vintage and technical forums.

I just received the following compression and leakdown data for a type 209 engine (e.g., 1960s 330 GT). Any opinions and rationale for their interpretation would be greatly appreciated. I know that there have been a few other posts like this, but as every set of numbers is a bit different, I'd like to hear people's reactions to these particular results. Thank you in advance.

cylinder 1: compression = 155; leakdown = 8% [apparent source, crankcase]
cylinder 2: compression = 165; leakdown = 10% [apparent source, crankcase & minor exhaust valve leak]
cylinder 3: compression = 155; leakdown = 13% [apparent source, crankcase & exhaust valve]
cylinder 4: compression = 140; leakdown = 24% [apparent source, crankcase & minor exhaust valve leak]
cylinder 5: compression = 160; leakdown = 18% [apparent source, crankcase & exhaust valve]
cylinder 6: compression = 155; leakdown = 20% [apparent source, crankcase]
cylinder 7: compression = 158; leakdown = 20% [apparent source, crankcase]
cylinder 8: compression = 155; leakdown = 12% [apparent source, crankcase & minor exhaust valve leak]
cylinder 9: compression = 145; leakdown = 18% [apparent source, crankcase]
cylinder 10: compression = 140; leakdown = 4% [apparent source, crankcase]
cylinder 11: compression = 155; leakdown = 24% [apparent source, crankcase]
cylinder 12: compression = 150; leakdown = 20% [apparent source, crankcase]
