You are. Much more and you run out of traction. Running out of tire is a curse, not a sign of improvement. You may have even improved something else, maybe body positioning, so that you're not using all your tire.
Stop hanging out on squid sites that proclaim the absense of chicken strips as the benchmark of riding ability.

I wish I had a quote of this somewhere on paper.... Jeff (Hawkster) said it to me at SOW I think... something along the lines of "People look out on a track and see great riders and their speed, but what they don't see is the hundreds of hours of practice and work that it took to get that fast" (Sorry for butchering your quote Jeff). The point is, motorcycle riding skill isn't a race, until you're actually in a literal race.
