2025-12-19 LOTS OF UPDATES: I have finally returned to this project to start doing some data analysis. I am currently working on a bunch of features to help clean up some of the data: ability to "swap" cassettes post ride if your settings were wrong during the ride, ability to see average gear ratio and average gear combo, plus some general UI improvements.

2024-01-01 IMPORTANT: I woke up this morning to a completely dead SSD and another one currently failing. No data has been lost, but I've just purchased two new drives so there may be some downtime as I migrate data from the failing system drive to the new drive. The new second drive will continue to be a backup. Thankfully that is the drive that was dead!
