D76 1:1 TM100 EI 100 = 9.5min / EI 64 = 12min. With EI 64 time cannot be longer than with 100. Something wrong on that table or on me. Some explanation ? Tks.
Most every time and temp on the MDC for a developer and film combo is submitted by ordinary everyday people. Everyone has a different way of doing things like agitation or different and not so accurate thermometers, etc.. The MDC is just a starting place. Of course the best place to start is with the manufacture and hone your technique from there.
There is always "something" wrong with the table. ;-)
I use the MDC only if I cannot get more reliable information from some other source.
Any time you see illogical data, you can bring it to the attention of Jon Mided at sales@digitaltruth.com, and he will correct it, if he thinks a correction is indicated.
Use Kodak's website to find development information for Kodak's films such as D76. Massive Development is open to anyone is able to add information regardless of their lack of knowledge and therefore is susceptible to data base contamination. MD while usually correct, should an information source of last resort.
