Maybe I'm narcissistic, but I always thought your SV passing me on my 1199 was the single highlight of your track career....
To the OP - not sure if this has been said and I missed it - but RE: tire warmers, you don't even really NEED to worry about those until you get up to race tires. There are Good street tires (Q3's, Diablo Supercorsa SP's) << Track day tires (Diablo Superbike Pro's, etc.) << Race tires (Diablo Superbikes, GP-A's, Supercorsa SC's) (track day and race tires can be a DOT tread pattern, or they can be slicks...the compound is the important part).
Race tires are like hockey pucks until they warm up, and they get these nasty little things called cold tears if you ride them too hard before they're warmed up.
Note - this is coming from a guy that used to run warmers on Supercorsa SP's (i.e. street tires). Absolutely, totally, (maybe even comically) unnecessary, but a friend sold me some for like $100 bucks after my third track day and it gave me some piece of mind.
Now to talk out of both sides of my mouth - while you don't NEED to worry about warmers until you're on race tires, and you're racing into T1 (Trackrat was running race compound tires last time I was with him at NYST and he was killing it after a lap or so), I tended to run them as a track day rider because if you're riding 15 minute sessions, and you have to take 1-2 laps at a pace where you may not be having as much fun / learning as much, well then that's 2-4 minutes of your time (or 15-25% of your precious track time). The same argument holds if you agree that you should't run at full pace on your first lap on a track day anyways. In that case, you're running at 75% (if, as nhbubba said, you can tell what 75% is), but your risk of tire slippage is the same as if you were running at, say, 90% of full pace. So even if you don't go hard out of the gate, warmers can give you a margin of safety on the first lap.
I'd put in a couple days though before I thought about making any kind of unnecessary investment like that though. Spend that first lap or two going slow and really, really focusing on body position and nailing the line (focus on these two things never, ever completely goes away - even Marquez has to work on scrubbing the paint off of different parts of his leather's shoulders ). Costs escalate quickly, so if you do decide to get out early no reason to have invested a bunch of money.
