Something like this which gives 90 tickets for 80 stamina (from DMM version)

Well, that's upto 90 tickets for 80 stamina. But with the more than odd randomizer, and only 2 of the chest being guaranteed, it'll probably end up more like "generally 30 tickets for 80 stamina, but occasionally a couple more"
