What we did in the day:

Buy at least 100 rolls of the same emulsion batch. Run several test rolls 
shooting and viewing in the intended conditions. Examine the results 
carefully and expose and filter the rest of the rolls to suit.

Any change in either shooting or viewing conditions, or, a different 
emulsion batch requires retesting.

As films age, their colour rendition and speed changes, you can either 
expose/filter to suit the film's current specs or wait until it shifts to a 
more favourable colour rendition. Freeze Kodachrome to slow the aging 
process.

John
