Allan, I don't believe paint reflections have anything to do with the irregular intervals in the scale. What I believe these numbers do reflect is despite my most careful measuring and mixing in small batches, my proportional mixing was off target from the beginning.
As careful as you intend to be with your new color mixing scale, it is easy to be slightly off and inconsistent with proportional measurement, especially in small quantities. What you think is a 7:1 ratio may in fact be a 7.1:0.9 ratio. This example should illustrate and explain the inconsistencies in my numbers. But as long as you know what numbers you have made, you will be fine.
