Calibrate Tx voltage

I saw an old thread dealing with this issue but no resolution. My devo 10 shows .8 mah lower than the actual value in my life battery. Are their any updates for this problem?

as far as i remember there's no way to make this work for every voltage level due to the way it's measured/calculated, just for instance it may be accurate at 12v and again at 9v but in-between it can be off as much as 0.1v. it's never going to be bang on throughout the full voltage range

Normally there is a multiplier and an offset, somewhere in the software.I can,t remember but indeed I think it was once idea instead of having fixed value, to have it in hardware.ini

That would be a great idea!
