The rule of thumb I've always used and has always worked is 1oz developer
for 20 sq.in. of film. If you're using a compensating developer its
1oz/10sq.in. So your one 8x10 and four 6 1/2x8 1/2's total around 300
sq.in. so you'd need 30 oz. of regular developer or 60 oz. of compensator.
Yup, your developer pooped out. I don't think the push development makes as
much difference as the sq.in. of film developed.
