Missing DFPM tab

I have a iAero and Powertap. I am running the most current version of iBike for Mac (5.0.7 I think). The software recognized the DFPM data but the tab that is supposed to appear on the main screen giving DFPM options is not there. I can't find any preference options to turn it on or off so I'm at a loss. Any suggestions?

Thanks for looking this over. Incidentally - would you comment on the differences in power readings during the intervals? I suspect it is related to position (I was tucked during the intervals).

Your DFPM data is in there, just fine!

Make sure to check the "Advanced Stats" box. You get to this box in the "Show" button at the top right of the main window.

Your CdA number (0.41) is really high for a person of your total bike/body weight (168). I guessed that a more appropriate CdA would be 0.35.

With the lower weight, your two units are very close. See attached ride file

Also, for best accuracy, you should maintain your usual ride position.

Thanks, John. I'll poke around and find out how to adjust the Cda.
