it won't make any practical difference to CR, the volume change is very small. A 0.5mm skim will remove very approximately 1cc from the chamber volume.

ok, more specifically, that 0.5mm skim equates to approximately 1cc less chamber volume, which will geometrically increase the compression approximately 1.4% from standard.

Thought it might effect it more than that.
Mine has a comp of 7.8.1, so its still going to be very near that.
