Questions
How is the new wattage calculated?
Each existing power value is multiplied, then the offset is added. Records with no power are untouched.
Can I lower power, not raise it?
Yes. Use a factor below 1, or a negative offset.
Does this upload to Strava for me?
No. The file never leaves this device. Download and import it yourself if you want it on a platform.
