If an athlete works out inside versus outside (it's cold out there!)...

… his numbers will be lower than outside. How can I let Xert know he’s done the workout inside and can it make the adjustments based on that? I’ve found indoor numbers to be almost 10% lower (not quite…)

You can adjust each individual activity’s signature. Just be aware that the change gets passed on to future activities. There is only one signature in use by the system at a time.
