To put this in perspective - I'm an okay rider but no hero. I ride at the top of the intermediate/fast group at the track, and when I get the bugs out of my new track bike, should be able to graduate to the fast group.
There are some guys at the track who do track days and also race. They are on a different level to me - I have had them slice in underneath my line at the track and leave me behind like I'm standing still ... and I'm on a faster bike. Their corner speed is staggering - big respect.
I always used to see them with their warmers on the bikes in the pits, and take some small consolation in assuming that there were slicks under those warmers. So not only did these guys have big skills, but the advantage of slicks, too.
Got talking with them late last year ... nope, no slicks. They're running Racetec K2's, same as me!
Even bigger respect - and testament to what these tyres are capable of.
