Man that is tough to figure out. We were soured by a festival sponsor saying we would get 3K people a day at a rodeo we vended last year. We were luck to get 300 the first day and 1000 the second. It was a blatant, lie. We talked with several riders and rodeo staff and they told us they had never seen 2K out there let alone 3.
There is a thread here somewhere that has a formula. Something like you subtract 25% as people who would not eat at all, the divide the remaining number by number of food vendors, and that will give you the number you could possibly expect. Do a search for the correct formula.
