I did a 24 hour enduro in an integra (really light car*) on one set of azenis, no chunking, no real fall off in laptimes from the very first session to the very last. Tires still had lots of life left at the end.

FWIW I had the 615s when they first came out, so pre-K, and they got greasy and scary when hot. This was on a 2400# car in the touge of Okinawa, no way in hell I ever heated those the way I have heated tires on the Camaro and Z06 here on real tracks. That's always stuck in the back of my mind. I know the compound has changed, but I never really hear of people raving about these tires for track days, HPDE, etc even if they are the Formula D tire of choice. I'd caution you about trying to get a contingency deal from Falken though, you'd be stepping on NASA/Toyo toes.

The NT01's make more since to me but if we get a tire that last we don't need a contingency.

My understanding is that the 615K+ fixed the greasing issue...haven't read anyone having trouble with new compound tires specifically.
On contingency, my thought would be that we wouldn't pursue it given than the number of tires needed per season was drastically reduced. Even winning an event a weekend and finishing well in another, a top guy is spending 3-500 per event to stay on sticker RR's depending on how close to the top step of the podium he was. If Azenis last say, 3 weekends we're spending $250-275 per weekend on tires. If you don't get contingency, well...you guys can do math
I'm not looking to step on toes w.r.t. toyo and NASA, just trying to find a way to make our racing more cost effective and still just as much fun. TOYO makes the R1R which is a 200TW street tire, maybe we consider that option?
The NT01 is made by Nitto...so we'd still be leaving the toyo umbrella with that one, though I liked those tires on the ecobooze at COTA.

The RR is durable, it'll last 3-5 weekends in terms of rubber. It's the first weekend that's 2 seconds/lap faster that's the issue. If Toyo baked out the tires before they sold them we'd probably not be having this conversation.
A tire that's equally bad for 3 weekends would be excellent. A tire that's fast the first weekend and horrible forever after doesn't make for a good amateur race tire IMO.

I don't know the answer to this, I don't know that it's something we can count on...most people who look to get into the sport come at it from a car cost perspective and less on what consumables cost initially. At least that was my experience.
I'm coming at this from the angle that it's unsustainable to have a $10k race car and spend $6-8k on tires per season to be competitive.
That being said, I think CMC will be a more attractive landing spot for folks making the step to W2W if we have competitive operating costs. To attract more racers I think we should look to what Spec Corvette is doing w.r.t. social media presence, etc. Different subject for a different thread though...

It would be great to stay Toyo and maybe work some kind of contingency, I hear the R1R falls off pretty quick after a few laps though. I wonder what the best 200TW tire is for our application.
