Compression and compression ratio are two different aspects.
There will be a trend/correlation providing you only ever changed the ratio aspect. get a bit more complicated when you bring in valve timming.....which has massive affect on compression.
As does boost and charge temp in cylinder increase. But these are statics. As quoted in manuals and as tested with a spark plug replacement pressure gauge. 99% of passionford won't know their dynamic cr, 25% probably won't know what one is
