Solving the riddle of why “Gear Usage Rate” never worked on my Shimano R8170 12 Speed Di2 groupset this week with some online research and testing of the latest update released for the BT-DN300. With the 4.1.0 update Gear Usage Rate now works in the E-Tube app, but it’s not the only place you can track gear usage!

A few days early on the firmware update. As of Oct 24 firmware version 4.2.0 is now available for the FC-R8100-P/FC-R9200-P power meters (https://bike.shimano.com/en-US/e-tube/project/firmware.html). Any chance you can do an updated test of the Shimano power meter?
