Units

Unit per game refers to a standard monetary measurement – typically between 2-4% of your bankroll. For example, if your bankroll was $1000, one unit would be between $20 and $40. Then, if you noticed a system that had won 15 units over the season, you could easily calculate your earnings by taking the units earned and multiply them by your standard betting unit (in this case, $20 x 15 units = $300).
