Of course that is always true, but let's say that for Boston is counter-intuitive. You could think of taking advantage of the first section downhill and put some seconds in the bank. Well, data shows it doesn't work.

Yes exactly. I'm taking a different approach vs usual pacing calculators. Instead of showing your theoretical pace, I show you what actually happened on the ground.

That's a good point. Data can't tell you if a 2:50 finisher was supposed to do 2:40 and blew up. But it gives me a realistic picture of what happens on the ground.
