RaceCoach

RaceCoach is a personal autocross telemetry and coaching project built to help me get faster between runs.

The goal is simple: after each run, RaceCoach should answer one question:

What is the one thing I should change on the next run?

This project started as a way to compare RaceChrono Pro data between runs. It has since evolved into a diagnosis-based coaching tool that looks at driving behavior rather than just reporting raw telemetry.

2021 Days (11)

After hemming and hawing and interating with ChatGPT on various models, I bought a Specialized Levo Comp Alloy gen 3. Cycle sport had a few left in their inventory and had dropped the price to about half of MSRP and built it with an upgraded drivetrain and brakes.

I took it out for its maiden voyage and am continuing to study all its settings and setup options.

Dear Buster:

At long last the letter I've promised for so long.

Introduction

Assetto Corsa has become my go-to tool for practicing autocross and track craft between real events. With Apple Silicon and CodeWeavers CrossOver Gaming, it now runs surprisingly well on macOS without needing a full Windows install or a virtual machine.

TL;DR: Best day ever for me. I hope to repeat this performance on another day. 

I let ChatGPT draft this based on my notes and data for the day.
