I know my system is conservative, but I'm normally cruising at 10,000 feet or higher at 24" MP, so I only have to lose 4 inches in the descent and I don't need to take it all off at once.
Best,

Yeah, I use 25", usually above 10K.
I prefer to be conservative in engine temperature management for a couple of reasons, CHT and "shock cooling" cylinders is one. Being "nice" to my turbochargers is another.
