I have a few rolls of Neopan 400 thats been pushed to 1600 and I'm wondering what the best times are for pushing XTol. 400 is rated at 9.75 for 1+1, and the data sheet for Neopan 400 in D76 pushed to 1600 undiluted is 16 1/2 min, where 400 is rated at 9 1/4. I'm thinking XTol 1+1 should be around 15 min. Any thoughts?
