11 races is totally worth the various amounts of pain I'm in at the moment. Dropping my times down into the low 61s was quite nice as well. Great day out there, thank you for organizing this, mav1c.
And I should add, if you are able to qualify for their "PRO" level, you can get a discount on future days. They offer a KTYFU (Kart 'Til You F-Up) for $85, which gets you as much racing as you can handle for the day before you get a black flag. Even with some of the slower traffic out there, colder tires and the occasional RX250 kart zipping by, I had zero black flags on the day. I'm definitely in for a future $85/day karting.
