910 vs 510 power numbers

I train capturing data with both devices. I notice that my there is a pretty big differential between the two at the end of a ride. The 510 consistently says I'm putting out about 10-15 higher average watts. Does anyone else see this? and if you do, which numbers do you use (or more importantly... do you find more accurate?)

    What type of PM do you have?
    Are you using both devices off of the same ANT+ signal?

    I use a Quark Riken and calibrate the 510 and 910 every ride

    Check to see if the non-zero averaging is set differently in each device. Sounds like the 510 might be set to OFF and the 910 set to ON.

    Nailed it Bob... thanks... 

    So I guess removing the zeros (if you're on the trainer) would remove any time the data drops? That would be a better measure on the trainer where you are constantly pedaling... but if you're outside you would want to include them because you want the data to average in the coasting? 

    I guess I'm really asking what to set them to?

    I always have it set to ON. The NP number you get from any ride kind of/sort of/more or less factors in the zeroes so as long as you're getting a NP I wouldn't worry about gaming the trainer number.
