Basically all of these options have varying levels of error/drift.
I’d wait for Greg to release v4 of the driver before ordering anything. It seems like he will release it in a day or two *crosses fingers*.
Whatever options you come up with in v4, do you think it’d be possible to have the reset calibration button mapped in some way that doesn’t require me to bend over and hold buttons down on my feet every so often? I don’t mind the drift as much as I do the fact that I have to physically bend down to reset the calibration.
