Thank you for taking the tie to answer my questions. Now, I have a few more.

I will be testing everything using Ansel's methods; however, I am curious to see someone's BTZS curves for FP4+ in 1:1:100. Specifically developing time vs. N and EFS vs. N. I wonder how different these will be from my estimate using Ansel's method.

I am leaving for vacation and won't have my enlarger fixed before I leave. Thus, I can't use the BTZS methods to make curves myself. I would be interested in what the BTZS curves say before I leave.
