Current Deck Heights & Other Numbers

Curious what's current these days in terms of typical block deck height, rod length, and stroke for a few of the blown (screw) Pro alcohol classes. TAFC, TAD, PM, and Outlaw PM. Some rough numbers would be helpful for what I'm doing.

I'm going to assume that a 4.000 to 4.150 crank is pretty typical, correct? Or are people running even less stroke these days? The deck height and rod length being used is my main focus. Had a guy mention to me that the decks and rods both seem to be shrinking these days, with good results to be had. Wanted to to see if this is generally the case or not?

Thanks.
