Just in time for another stage race with a long TT my PowerTap is acting funny again. It does this sometimes, where it reads really low for a minute or two, but it usually bounces back to normal, and I've been chalking it up to regularly riding and racing in monsoon-like conditions as of late.

Today it seemed to last for a while though--any thoughts? I don't think it's the battery, since I replaced that a month ago, and when that went I would get a blank instead of a 0 or a low reading. I'm hoping that it will magically be okay tonight, but is there anything I should do if it's still wonky, aside from killing myself?
