I processed a batch of fp4+ - 135 in Rodinol 1:50 @ 20c for 5. 7, 10
and 13 minutes. The B+F readings that I got were 0.29. This seems a
little high to me. Is this a normal B+F for this film?

thanks in advance

No, it is not normal. In my experience with various developers FP4+ has
always had a low B+F, about 0.05- 0.07.

A density of 0.29 for B+F IS normal for 35 mm film whereas 120 roll
film has B+F around 0.08, both FP4+ in D-76 normal contrast.
