BB/hour (big blinds per hour) is the most comparable winrate metric across different stake levels because it normalizes results by the big blind value of each game. In live cash games, typical strong regular winrates are 10-20 BB/hour; in online cash games, winrates are expressed in BB/100 hands and converted to per-hour based on hands per hour volume. Comparing BB/hour across different games, rooms, or formats enables informed decisions about time allocation and game selection. In tournaments, the equivalent metric is ROI (%) and frequently BB/tournament considering blind escalating structure.
