Replying to Total (Base + side) Edge Angle Calculation Question

Okay so my question is about your ski base angle and edge angle and how it works together to create an angle.

So I’ve read up online a lot and I’ve seen some confusing stuff. A lot of people talk about base bevel and edge angle separately but touch very little on the total angle. Here is my question:

Say I put a 1.5 degree base bevel. Wouldn’t this put my total edge as a 91.5 degree angle? Then, if I put in a 2 degree side angle, it would drop my total angle 2 degrees to 89.5 degrees. Therefore, I’d have a 0.5 total edge (90-0.5 = 89.5). And a 1/1 would be a 90 degree total edge angle.
Am I correct in this calculation?
