making a new profile from an old one

[namblor]

I've been riding with my 1st profile, and am very pleased with the metrics it is producing, but I want to make a new one with my summer gear/wheels. If I'm not mistaken, all I have to do is coastdowns. But I can't seem to find the instructions of how to put it all together.

Do I copy profile 1, send it to the ibike, then do coastdowns?
Do I go do the coast downs, then copy the profile, then put it together?
Not sure how this part works.

I know this is easy, I just don't want to mess it up. (typing with one eye on this screen, the other on the Giro)

If you have a good wind scaling value, then you can do the coastdowns. . .make a profile with coastdowns only, and then copy and paste your wind scaling and riding tilt values into the profile that will be made that will be titled "c-d only"

With a different set of wheels, you may have a different crr value and friction. The wind scaling should stay the same - it is the same unit. I have a set of aero wheels and regular rims (both are Mavic). These produce different friction and crr, but for all purposes, the wind scaling is identical.
