Ruler & Snap To Ruler Inconsistent

The Ruler in Scrivener is displaying inches with increments of 1", 1/2", 1/4" & 1/6". The snap to ruler function however has increments of: .125", .250", .375", .5", etc…

This results in the ruler often snapping to positions unmarked on the ruler. It would be nice if these two could be linked toegther with something like a snap to line or other incremental option. It would just make everything feel more consistent.
