My objective assessment is that flatballer read your post as you thinking you were not far away from dong 24mph yourself based on how quickly you got to 20mph. That's how I read it at first as well, hence the comment that improving to 24mph is now the same as going from 16 to 20.
Nah, I was responding to the posts saying that 24mph was TdF-level speed (if only... that might make my speeds somewhat respectable). Normally I'd quote what I was replying to, not sure why I didnt this time.
