Well FYI, cyl is generally converted into minus cyl, the axis flips 180. So your first two measurements of cyl are close together.

Also cyl/sphere differential is also hard to determine but often follows a pattern in that you can overcompensate in sphere for cyl and vice versa.

Not even going to begin to go into the effects of possible tolerance differential, prism imbalance, and that is just with Single Vision Lenses.

Also you generally have 90 days as industry standard to go back and retest your RX.
