PP overly sensitive to wind?

Post by flahutewannabe »

In month 2 of using my PP and I think it's getting dialed in, but I'm wondering about wind scaling. Seems like I get pretty big variations in power with what I think are not so big changes in wind. But I may be off in my thinking. Attached are two recent ride files for review. Thanks!

You have the "auto analyze" function turned on. Please turn it off in Edit/Preferences/Analysis

The auto analyze is magnifying the effects of wind. Once it is off I think you will see less sensitivity to wind.

Thanks, John. Found the setting and changed it in Isaaac. Does this change the profile and need a "send profile to device" update to the PP itself?

Nope, no need to change anything else.

Thanks, John. So I can see where this would adjust the graphs and data in Isaac, but how do the watts displayed while riding adjust for this? The real-time (dynamic smoothing on) numbers are where I noticed the variations seemed to swing a lot.

The variations you see in your ride file are MORE than the variations you will see on the road. DPS is not used in the ride file.

I really think everything is OK...
