Hey, are there any improvements to the Erg mode on the roadmap for Zwift when controlling the wattbike atom?

The resistance (and hence power output) varies a lot in comparison with the erg mode in the Wattbike Hub app. This used to occur with the WattBike Hub app to but was improved by software/firmware improvements.

I can supply output files if it would help with dev.
