The Theoretical Return Rate of a bet or ‘TRR’
Sports betting loyalty programme: everything you need to know about TRR!
Each bet has its own theoretical return rate, also known as ‘TRR’. This is used to calculate points for ‘Supercharged’ and miles for sports betting activities, as well as for the associated loyalty programme. In other words, the points earned to increase the ‘Supercharged’ gauge or the miles accumulated depend on what a bet theoretically pays out to the player who placed it, regardless of the outcome of the bet.
‘Theoretical Return Rate’: the formula
The formula for the theoretical return rate for a ‘single bet’ is written as follows: TRR = Probability x Odds.
When it comes to a ‘combined bet’ eligible for the Combo Booster, the formula becomes: TRR = Probability x (Odds + %Theoretical Combo Booster x (Odds-1)) where:
- Probability : odds of the event minus commission,
- %Theoretical ComboBooster = proba(rank1) * max(% rank1 of initial draw ; % rank1 of level after completion) + proba(rank2) * max(% rank2 of initial draw ; % rank1 of level after completion) +proba(rank3) * max(% rank3 of initial draw ; % rank1 of level after completion) + proba(rank4) * max(% rank4 of initial draw ; % rank1 of level after completion) + proba(rank5) * max(% rank5 of initial draw ; % rank1 of level after completion) + proba(rank6) * max(% rank6 of initial draw; % rank1 of level after completion)
A few exemples
Simple bet
For the PSG-Inter match, you bet on a “draw” at odds of 3.5 and a probability of 28%.
The theoretical return rate or “TRT” will be: 0.28 x 3.5 = 98%
Combo bet
You place a combination bet of 10 selections at odds of 10 and a probability of 8%. The value of the Combo Booster can be between 8% and 160%, and its theoretical value will therefore be equal to 17.92%.
The theoretical return rate or “TRT” will be: 0.08 x (10 + (10-1) x 0.1792) = 92.90 %
