Indoor to outdoor power readings

Hi sorry if this had been a thread before, but had my powetap for around 3 months now and been building my FTP. With the snow and ice I havnt had the chance to go out and train outside, FTP inside on the turbo is 255. When I ventured out today, my readings were so much higher and felt so much easier! Is this normal, or have I suddenly become cancellera over a few months ??

Guess there are lots of variations to consider, heat resistance wind terrain etc, funny ad you would think it would be easier on turbo, harder outside
Up hup hup hup.....fricking hate that!

    I've just done a ftp test and I'm pretty certain that my power indoors is the same (or maybe even higher) as outdoors.

    For me there are a couple of factors that balance them selves out though:-

    Indoors: done sitting up, outdoors done in tt bars.
    Indoors less motivation but the big one for me, indoors I can keep a steady power output where as outdoors my power can wonder depending on the terrain, in other words I can better pace an indoor effort.

    I think the trick is to do all your testing the same way. Whether it's sat upright on the turbo or on a particular stretch of road.

    Then you can track changes better.
