Problems importing date in to Golden Cheetah

joeyhalloranjoeyhalloran Posts: 805
Hi, I did a work out tonight, 1 min on/1 min off at ~330W-350W for the on and ~150w-200w for the off (at least that was my intention). I loaded the data in to poweragent and the graph looks nice, big peaks and big troughs. It says my NP was 285W for the work out (not too shabby for me).

Poweragent (very annoyingly) asks if you want to clear your powertap after uploading and I accidentally clicked "yes". When I try exporting the file as .CSV and importing the file to golden cheetah I DON'T GET THE SAME RIDE, I just don't understand what it has done.

GC claims I did the "on" at around 250W-260W and the off at 230W-240W and as a result my NP is down to 266W.

1) is there a better way to import data files to GC?
2) will the difference in NP have a difference on my bikescore/Daniels point? (This is really why I am using GC, obviously i've done what i've done so a figure on the comp can't change my workout.)

    I didn't think Poweragent did normalized power.


    Is there a new version of the software?
  • There may be, if you go into the power detail tab it has it there.

    FWIW I have V 7.5.1.10 apparently.

    Looks like there is a new version! 7.5.1.19 downloading now :)


    EDIT: Doesn't launch at all. Great. :?

    Take a look in the 'Editor' tab and see if the data looks correct ... look out for red wiggly lines underneath any of the values.

    If you can, send me the file and i'll take a look to see if there is anything untoward.

    More likely is our obsession with not ignoring pauses... the NP algorithm tends to ignore <30s pauses which often inflates NP quite markedly. Its a strategy to overcome issues with drops in recording -- in GC if you didn't record it, it didn't happen :)

    How can I sent you the file? I did briefly stop (about 10 seconds) but I wouldn't have thought it would change the whole ride profile?

    and surely ignoring 0 values would mean the NP would be higher wouldn't it?
