A Question About Decarboxylation

I've read from multiple sources, including a discussion on this forum, that the best way to make potent cannabutter is to decarboxylate the green beforehand to turn THCA in to the psychoactive THC. My question is, if I'm using the cannabutter to make something that needs to be cooked at a higher temperature than the decarboxylation occurs, will the cannaboids evaporate? Specifically, I'm making a cheesecake and baking the butter in to the crust. The baking temperature for the cheesecake is 350 degrees, 100 higher than the temperature used for decarboxylation. I want to make it as potent as possible, but I don't want to risk losing precious THC.

Im also curious about this. Decarbing, from what I have read, is simply heating the plant matter up a bit before you cook with it. My question is, isnt the plant matter decarbed when you cook it into the butter you make? I usually crock pot my stuff for 12-24 hours. Wouldnt this do the trick?

This graph explains it well. It's time over temperature.

Note, cooking a cake or brownies, the middle is not at its cooking temp for long.

So the general decarb rule would be 293F for 7 minutes to get the most for your money, right? Also, I assume this chart is not exponential. Would you happen to know when the cutoff would be for maximum effectiveness?

here are a couple good links about de carb

snaps, much appreciated!!!!!!! ive been doing it wrong apparently. I was doing the 190* for 45 mins. ill now try the 293* for 7 mins. since my gas oven doesn't do 293 (either 290 or 295), ill give the 290* a shot this next go with my muffins. pumpkin spice muffins for Halloween.
