We don't guess.
We measure.
TreadPilot drives a real treadmill belt, so its behaviour is not a matter of taste. Every decision is backed by research — published science, what commercial treadmills actually do, and simulations calibrated against real workout logs — and every note here is the write-up: in plain language, charts included.
Reaching the zone should not take 20 minutes
A dropped Watch signal sent one real workout to a 3.0 km/h crawl, and the controller took 20 minutes to reach the 130–145 zone. The log shows why, and three planned changes cut that to about six minutes in simulation — with zero overshoots in 210 stress runs.

A heart-rate segment rode the bottom edge of its band for a whole workout — the rule working exactly as written, and written wrong. The next update will push to the lower-middle of the band and then go quiet: a better parking spot which, in simulation, costs no extra speed changes.
