How it works: implied probability uses −A → A/(A+100) and +B → 100/(B+100). The extra win probability you need from buying = implied probability of the new price minus that of the old price. Whether buying the half point actually gains that much depends on how often games land on the numbers crossed — that is the sourced data still pending.
