Running multi day events at tracks all over will definitely teach you a few things.

Time shot or two Thursday. Couple of rounds Friday and Saturday. And if you're still in, last couple of rounds Sunday, hot lapping you because they want to wrap it up.

And if it rains...we got a time shot and a couple of rounds in at Englishtown one year, Thursday and early Friday, and it started to rain. Rained until Tuesday. Unload it and race.

Everyone is in the same boat. Just have to know your car.
