Questions about Coast Downs
Posted: Sun Apr 24, 2011 4:31 pm
I bought a new bike and went thru the process of setting up a new Profile for the new bike.
I forgot that the Coast Downs are supposed to be AFTER the Calibration Ride so I did the Coast Downs first. That was mistake #1.
I did 8 C-D's but did them in each direction instead of going back to where the first one started. In other words, I went South with a bit of tailwind and then back North with a bit of headwind, then repeated this 4 times. Mistake #2!
So I would like to know if this data will be accurate!
For instance, do I use ALL the C-D's to create this Profile, OR should I use ONLY the Coast Downs done in the same direction? I looked at the Profile 3 ways: All C-D's, odd-number C-D's and even-number C-D's, each had different coefficients. And which would be the most "accurate"?
Which Profile data should I use? Also, does it really matter that I did the Coast Downs BEFORE the Cal Ride (which was 2 miles each way)?
Can someone help me with this?
thanks!
