. What sort of ratio of Hobbs
to tach time would you expect?

I've recall a figure of about .8 for planes used at flight schools. Of
course, that's going to vary widely depending on the nature of usage and
location, but on average, .8 or a little higher. All you could use the
figure for would be an approximate anticipated figure, anyway. Your real
figures could only be determined after-the-fact.
