I'm a new owner of an iBike. I performed a cal ride (the second one) and did 4 miles. I tried some coast downs but got bad coast everytime.
I happen to have a PT wheel on loan at the moment and both the iBike and the yelow head unit seemed to be showing close after the cal ride.
When I look at the ride after it had no cadence info. I fixed that (and the cal ride) using the repair missing cadence function. However I'm now concerned there is no cadence info in the cal ride the profile using the coast downs says

If I try and use the DFPM data I get it to sync nicely but then this screen comes up making me believe the cadence is indeed missing.

So, can I repair the cadence in the cal ride or do I have to do it all again? If I can't repair it how can I be sure the situation wont arise the next time as at no point did it tell me there was no cadence data.
Thanks
Ant
