I think there is a lot of push from parents and sometimes the skaters themselves to measure success by jumps, perhaps because it is a visible measure of progress, but the focus on jumps is often at the expense of skating skills, which are the fundamental building blocks of skating. It's a delicate balancing act, but it's very hard to go back and and improve speed and use of the blade after the fact. Yes, it can be done, but it takes a LOT of effort and focus and it's really the exception when a skater significantly improves their blade skills later in their development cycle. On the other hand, revolutions can be added later if the technique for the basic jump is sound (see Tuktamysheva, Liza).
Patrick Chan got to be Patrick Chan because his coach relentlessly drilled him on basic skating, day in and day out, from a very early age.
