MethodIn-depth guide
Change one thing, then re-check
The fastest way to a good fit is small, reversible steps you can actually measure.

Make the trial traceable
Keep a bike-linked history
Store the coordinates and adjustment history needed to undo a change or repeat the check.
Open toolIt's tempting to change saddle height, fore-aft and bars all at once. If three coordinates change, the next recording cannot isolate which one produced the observed 2D difference.
Make one small change at a time, record the exact coordinate, then re-record with the same protocol. The app compares the difference with observed measurement noise.
A preserved baseline and reversal route keep the mechanical experiment understandable and reversible.
