Long story short, I have done 2 O&B rides on the same bike, with the same everything - & have 2 somewhat different calibration results.
Same route, so apart from the wind I can't figure out where the difference comes from & whether one, both or neither is correct.
What am I missing??
1: Aero 0.781 Wind Scaling 2.301
2: Aero 0.675 Wind Scaling 1.989
The difference seems to be a difference of 15-25 watts (average) when tested against rides from last year which used a completely different profile to either of these (change of profile after the event). That's roughly a 10% error.
