Be careful when using the MDC to pick a development time. The publisher collects data from a variety of sources, some not particularly reliable, does not check for accuracy, and just adds to the Chart. Most of it is fine, but there some significant errors, so for first time use of a particular film and developer, process a low value or test film strip to see how it comes out. Frankly, there is no reason not to use the development data provided by the film or developer maker, at least where they provide the information. Treat the MDC as "experimental". A lot of folks go straight to the MDC and treat it as holy writ because (1) almost no YT videos mention its problems, and (2) it has a download app which lets you synch its data and run a process timer on your smartphone (if that's a good enough reason to blow off your roll of film).
Good advice. I did hear the Trix 400 time is wrong on the big Dev chart and most apps that use it. My results are usually fine. Although I think I do trust the all a little blindly..the notes part of the app contains comments by other users and often they let me know any info not obviouse
@@dangerpowers123 I have not studied the issue in detail, but I'm aware that there is at least on HP-5+ recommendation that gives a development time which is stated as "normal" but actually gives a full stop push process. The practical problem with the MDC is that to use it safely, you have to cross-check its data against real sources for film and/or developer data, in which case why use the MDC at all. It's virtue is that it presents development data for a wide range of irregular uses with odd film/developer combinations and wide ranging push and pull processing. So, it's more of a starting point for experimentation. However, IMO on YT it is often recommended because it has its neat little process timer app which dovetails nicely for those addicted to their smart phones. A wet darkroom setting would be the last place I'd use my wet hands to play with my expensive smart phone, when you can buy a digital waterproof timer for less than $15.

Great video mate
Thank you, 😀👍🏻
