I'm guessing that 3 min savings is at or about 300W (what most tests quote), going 40k into the same wind conditions the entire way. Probably dead flat, no tail wind sections...
That was the basis for my post above. Take a 2k 105 road bike with decent tires, real world conditions with stop lights, traffic, head/cross/tail winds, dogs - and the real biggie - being human and not holding 300w for an hour - how much time does that extra $5-8k really save? A minute? No time if you get stuck at a few redlights?
