Hmm. I've seen "plein" for full choke, which makes perfect sense. 3/4 would be improved modified. I can see the P in "IP" standing for plein, but in that case, what's the I stand for? A modifier of some sort, but that'd usually come after rather than before, as in LA (lisse ameliore). I'd vote for PP (presque plein)--almost full.
