## Experimental Profiles: Distorted Ellipsoidal Saddle (DES)
ver 1. Initial trial
ver 2. narrower top to emphasize dish similar to MT3.
ver 3. majority prefer SA's more forgiving edge to press accuracy.
widening top surface alone caused most of R2 presses to catch R3 caps.
* shifted R3 tops to
* increased dishing pitches
