The faster rider saves 1.7% which at 25mph is 60 seconds. The slower rider saves 1.7% which at 20mph is 75 seconds. There are certainly other factors which affect this relationship.
That's the problem. It's NOT a constant.
As a PERCENT OF OVERALL TIME a faster rider has a greater saving and that's all that matters. Talking about the TOTAL amount of time saved is a false metric that creates the marketing non-sense that prevails in the land of 20deg yaw angles.
