Re: Q3 Mileage
That particular picture I just looked up is from an Italian motorcycle website, the article was from back in 2007, so not quite modern day rubber on there. If I recall correctly it came with the old Dunlop D220 tires or something similar.

To be fair, I certainly wouldn't choose to run sport touring tires for a trackday, its not so much about outright grip, but more about better dealing with increased heat for a longer period. A sport touring tire is likely going to get overheated and greasy (assuming you're running above Novice group pace). But on the flip side, I have Dunlop NTEC slicks on my 600 that I'm only using for trackdays now (no more racing), and I'm strongly considering dropping down to the Q4s for trackday usage. They don't need warmers and will have plenty of grip for that application.
Honestly, for someone looking into their first trackdays ST tires are just fine; you have to run them really hard for overheating to become a problem, but that is not the point.
My point is about running hypersports vs. race DOTs; at what kind of pace would a Q3+ become a limiting factor that would require a switch to, say, a Q4 or a race tire? I'm a midpack A group at best, when I'm having a really good day; if there are pro-racers mixed in A group in that trackday I know very well to make way for them; I'm thoroughly convinced I've never reached the limit of hypersport tires and that running race DOTs will actually be detrimental as I might not even load them enough to build up heat. You can always deflate them to increase flex and heat them up, but at that point it's just money down the drain.
I started doing trackdays a few years ago; remember when the Pilot Power was just released? About that time. My first track bike was a Katana 750, with bias ply tires! Nowadays the Pilot Power succesor, the 2CT, is a cheapo entry level tire! Tire technology has come a long way; quoting people that actually know what they are saying, Dave Moss said in one of his videos tire technology has advanced far more rapidly than chassis development over the last 15 years; thus their '05 GSXR 750 project bike. I have a feeling that a Q3+ can outperform a race DOT from 15 years ago and I'm nowhere near the pace pro racers were setting 15 years ago.
