Maybe, but as you say, since the pie is smaller, is 1/10th of a KpH any more or less strange or insignificant than, say, 50% of 1/60th of minute?! It’s all kind of vanishingly small, no matter how it’s sliced and diced, and personally, I don’t worry about it at the micro level, and instead just do my best to be reasonably light, reasonably aero, reasonably fit, and extremely hopeful it all works out in the end!
