I'm looking for a formula for soak times in a salt bath hardening furnace.

Can you come back with more information related to the material you intend to use and heat treatment objectives?

The advantage with the salt bath is that it provides a uniform temperature gradient for austenitizing and tempering operations

Watch the temperature of your bath.
Watch the temperature recovery after adding parts especially if there is any mass. We had two salt baths with the same volume of salt except that one was a much higher wattage and recovered very quickly. While the other took 4-5 times as long for the same size part/parts.
Keep the bath clean and follow the manufacturers recommendation on salt rectification.
Now that you have the soak times down pat you should look at the quenching. The use of a "fast quench oil" with your materials should give you some better properties.
Safety:
Have a good set of safety rules and well maintained equipment. Enforce the safety rules, especially the personal protective gear.
I walked into a shop that was using molten salt baths just as an accident was happening. There was bath eruption, cause unknown, that burned 5 personnel. One later died from secondary infections. I never will never forget trying to get the salt off the personnel.
Within weeks of the incident we started abandoning a very extensive molten salt (Hydride) cleaning process.
