the recommendation to charge to 100 started when Tesla failed to read battery % from their LFPs between 80-100%. the voltage difference ws so minute between 80-100% that the car wasn't able to give an accurate state of charge giving people inaccurate range.
so they recommended a weekly charge to 100% to calibrate the range meter.
true story.

The owners manual for the Tesla Model 3 with LFP literally recommends you charge to 100% for daily use.
