• using a p2m (not true left right power) my power is consistently around about 47%/53% balance.

    It doesnt level out when doing max efforts, eg I did a hour effort today that was a 60min power pb and my balance was 47/53. 5 min effort the other day was 48/52, 3hr club ride 48/52 etc

    Does it matter, is this within a normal range or a within the % of error that p2m esimates l/r balance. Anyone else with a p2m find it similar? Any other potential causes, short leg? tight hamstring etc?

  • It doesn't matter a jot.

  • Does it matter, is this within a normal range

    No, yes.
    If it changes a lot, there might be some significance to it, but the chances are that you'll already know you have a broken leg without looking at your power meter :)

  • My P2m used to do this, suggested my right leg did 5% more work than the left. Then I bought a second p2m and it showed the same trend, but with the opposite leg... So take from that what you wish.
