One other item that never seems to come up - In the wind tunnel the P5X and P5-6 (outside the margin of error) was slightly faster, very slightly ...... but unless you put our optimized chain on those two bikes ....all things being equal, the Tactical is faster on the road - just say'n :-)
Having pre-optimised equipment is one of the extras I was referring to and certainly takes away a lot of hassle for the rider.
However, the impact of the chain doesn't appear to negate the aero difference.
I can't find any data that you have released on the relative performance of your chain, but I do have the Ceramicspeed data in my model.
Which shows that for a leading AG rider on a low wind day the P5-6 with normal DA chain would still have a 35s advantage over the Tactical with optimised chain. In fact this difference applies for a wide range of riders (power/speed).
Of course -
to prove your point for a specific case - on a higher yaw day the combination of the Tacticals improvement at yaw and the chain cancel that entirely. But it's not possible (based on available data) to make a generalisation that the chain cancels the aero difference.
And, if we're really nitpicking (which is obviously something I like to do), the P5-6 is not the fastest configuration of that frame (as Grill will happily point out too), nor is it hard to get a good chain (from you or MSW or CS).
There is no dispute that the package you offer is an easy way for a rider to be competitively set up in every aspect out of the box. And that any remaining performance advantages are either uncommon or $$$. In no way am I trying to denigrate what you offer.
The point I'm contending is when people infer 'fastest' from data that doesn't show that.
(but it's fine to say "as fast in certain conditions" ;-))
