I undertook this project over Easter and thought it probably worth sharing to the technically inclined within this forum.

Hopefully it'll prove to be an interesting read to anyone who's ever wondered how alphas can be calculated with minimal computational overheads.

Working code is also included (written in Python) and is heavily commented to show it working in practice.


I am also hoping that COROS can use this to fix the alpha results on their watches. As far as I can tell the APEX Pro, VERTIX and VERTIX 2 don't enforce the 50m proximity requirement.
