Pushing FP4 @ 400 with D76

[Samsam]

hi guys,
last day i took pictures to test pushing process. I know that FP4 and D76 are not the perfect match for this purpose but it's all i got.
Tonight i'll process this film but i need some advices first
I use to process fp4 @ 100 with D76 for 9 minutes with greats results, should i developp fp4 @ 400 for 13,5 minutes ?
hope you can help me 🙂

well, it's like 20% to 200/250, then 20% more for 400/560. So that's about...about 12-13 minutes I think. Just off the top of my head using the standard rule. A quick google at photo.net might help.
