I use Toyota FIPG and don’t wait any time before torquing. Granted laying a bead, installing the gaskets, baffle, pick up tube, another bead, laying the pan on top of all this, and finally torquing is probably a ~20 minute ordeal. But I never have leaks.

You're correct, but there's also (usually, not sure for every brand but the Wurth stuff I used to use did) a specified time you're supposed to let it skin before putting parts together.
Usually it's: Apply bead, leave for X minutes, then join parts and torque.
Basically, you let it part cure so it's still sticky and pliable, but not totally set.
Join too early and when you torque the pieces up it may just ooze out the sides and leave a tiny amount of RTV that wont seal well.
Join too late and it's too firm to conform to crap surfaces and will leak.
TLDR:
read the label.

I wish we had that over here... I used it for a couple years on various projects when I was in the US, and that thing is pure magic.
I use grey silicone and it skins for about 20 minutes while I do all the stuff Curly mentioned above.
Not only it never leaks, separating the pan from the block gets pretty difficult if you ever have to remove the pan for whatever reason.
