Default Compression Ratio of a 1.6?

Does anyone happen to know the Dynamic Compression Ratio of the 1.6l motor (manual trans motor)?

Dynamic compression ratio is very specific.

The static compression is 9.4 where as the dynamic ratio changes based on tune, rpm, throttle opening boost. basically Dynamic compression is the static ratio multiplied by the map value making it into the cylinder (in kpa) divided by 101.

Sorry how did you eventually come up with that conclusion, Either your asking for a different thing to what I thought or ive got something way wrong here.

I did at 200ft alt
Boost pressure doesn't seem to change DCR, inlet valve closing ABDC does by a lot.
Sure its DCR for reason, and this probably at one point
