Not sure what you mean? I calibrate my Stages before every ride (although according to the DCRainmaker review there may be less need to do it so regularly compared to some others).

I've certainly heard about growing pains with Stages, just like there are always stories about the other major meters out there that are not always positive. I do think that the easy updates with Stages is a nice feature. Ultimately though stuff happens and it's how the company deals with those problems that define them, sounds like Quark and Stages have stepped up to the plate as often as necessary from a customer service stand point.
