Figured it out. The TT bike meter does read low. I did a trainer test back to back to another Stages meter and it does read 20 to 30w lower.

I made a chart and recorded power at 4 speeds on both, twice. And it is low. Now I know though.

The math from my dq TT race meant for the power to make sense, my CRR and CdA had to be about .003 and .170z. Not possible for the aero. Adding in the low power, it takes adding 30w to get the CdA in the calculator up to a more understandable .200.
