I developed the second roll of T-Max 400 in Fujifilm Super Prodol (SPD). I looked at various numbers on the MDC and found it all rather confusing. Anyway, I decided to use a very generic number and developed it for 7 minutes, the same as I did with the T-Max developer. The good news is that I thought the results were just fine!
And, when you take time to fine tune the results you will likely get something even better than 'just fine' and turn to excellent. A developer undeniably has some characteristics that make it unique. In reality though, most of those differences can be overcome by altering technique. It's mainly a thing of sinking your teeth into it and finding the best way.
