⚠️ Auto-TPI is an experimental new feature that will allow the system to calculate the TPI coefficients automatically. This is an experimental but tested feature since november 2025. You can safely configure it if you want to test this new feature. If something goes wrong, you can always deactivate the auto TPI feature and re-set the TPI coefficients (defaults to 0.6 and 0.01).
Documentation on auto TPI is there
A big thanks to @KipK and @gael1980 which implements this very feature 👍
