Ted -- When MK was a faculty member of a workshop I assisted at, he passed out a sheet with suggested times based on the one's meter readings (times for Tri-X and Tmax400). And included were suggested times for both films at f5.6 under different night lighting conditions. I assume he created the times through personal experience. I hand them out to our students all the time...great starting points.
MK would often have more than one camera making exposures at the same time.
Can you share said sheet by any chance? Perhaps send a link via PM if it's not something that can be posted publically?
