Different TP of climbing and flat TT?

My TP increased twice as reported by Xert. Both brekathroughs were achieved at climbing at more than 20mins. Should I use that figure to plan a flat TT course at the same anticipated duration?

I have question because I read an article here -> https://cyclingtips.com/2013/09/climbing-and-time-trialling-how-power-outputs-are-affected/

You’ll need to judge this yourself. Xert merely provides you the data and can help you assess this. It may be because there is difference. it may be because you’re getting fitter. :slight_smile:
