How many fights per year would you like to see from fighters?

I would like them to fight once a month but that's not a reasonable ask, they have lives and famillies too. I think 3-4 a year for a top contender/champ. I think once a month for an up and comer, get a few wins under their belt and get some experience. Tyson fought 3 times in November of 1985 but that sort of stuff isn't sustainable at the top level, only when starting out. Historically it seems the longer time goes; fighters seem to have less fights.
