Do other dms playtest boss encounters? Obviously you can’t predict your players actions, but to vaguely balance things? I try to a little when time allows, but I fear I've lost that commodity over the years. Now, it's largely just relying on my experience with my fingers crossed!

Ever had a situation where you needed to do on-the-fly adjustment to balance things out, or sort of play the situation in a whole other way than what it actually would be? I’ve had some rare battles where the PCs completely surprised me and trivialized the fight, but I could see they wanted a meatier challenge, so I’d have a “second wave” enter to mix it up.

Yes. But I do it by running the same encounter several times over the years against many different groups. 😀 So by the third or fourth time, it's balanced as shit!
