Nope, I meant what I wrote. 8.3:1 to 9.3:1 is an increase of 10 points.

That's not 10 points, that's one point.

8:1 to 9:1 is one point.
eight "point" 5:1 to nine "point" 5:1 is one point in compression.
You are talking tenths of a point, not points.

If you raise a 8.0:1 ratio by 10 points, it's now 18.0:1.

Not hard written, but in a static model, for every
point increase, the power output will change by approx. 2%, until you get upwards of the 13 point mark, then it drops
to approx. 1.5% change.
