We don't subtract out tare drag...to arrive at our comparison #s

Why not? That is, what is the logic behind this decision?

Why? It's a constant unless you believe there's interaction between the bike and the struts that varies by bike as well as by yaw

No, that wasn't what I was attempting to imply...I just wondered why you wouldn't correct the data since you obviously have gone to the trouble of measuring the "wind on" tare.

So my question stands: does everyone else seem massively off the back once you put the tare drag back in?

Obviously not, but here is why I am confused: I've always understood that they do correct for the tare at TAMU*, and since my wife's bike and Gary's bike appeared to have similar drags, assumed that the same was true at the LSWT. That is why I am/was so impressed by the numbers that Mark keeps quoting for the Shiv.

*I know for a fact that they do when presenting bike+rider data.
