Classicpan 400 question

I have the experimentation bug, I want to pull Classicpan 400, rate it down to 200 asa and develop with Rodinal 1:50. The big skill testing question, how long? Nothing on the Massive Developing Chart covers this. Any experiences, thoughts?

*Classic pan is Forte film.- 200 is the real speed for daylight use and
400 for tungston.
* !5 min.

All the best.

Thanks for the info, to clarify is that 5 minutes or 15 minutes you put down and is that for 1:50 Rodinal?

Fifteen minute is much closer to the mark than five; my normal time for Classic 400 in Parodinal 1:50 (which uses the same times and dilutions Rodinal) is 16 minutes, though with agitation every 3rd minute (I like a little less contrast than some). I'd second the suggestion not to alter development, however; not because Classic Pan is a stop slower than the box speed (for me, it isn't, due to my extended, low-agitation development) but because you'll find it unnecessary to pull development.
