Which bets progression system does BIA use?
BIA adopts the split Kelly system for the management of bets, with which multiple advantages are achieved.
Taken a bankroll established by the bettor, the Kelly method compares the odds offered by the book (higher) with the real one (lower) and based on the ratio that comes out determines a stake proportionate to the cash available, so that you never run the risk of losing all the capital. Based on Kelly’s formula:
stake% of bankroll = (((odds offered by book x (1: odds processed by BIA)) – 1): (odds offered by bookie – 1)) x 100
By virtue of this formula, a higher percentage is played in the most favorable situations (example: price paid by the bookmaker is 2.00 while for the software the correct one should be 1.90) and less in unfavorable ones (example odds offered by the book 2.00, real odds 1.99).
As suggested above, furthermore, by periodically updating the bankroll we will obtain a capitalization of the earnings. If you do not withdraw your winnings but keep them in cash, you will enjoy the benefits deriving from the compound interest.
If you win 10% of $ 100 in the first month, you will have $ 110 at the start of the second month.
By performing the bets as indicated, the second month, for example, you still earn 10% of the bankroll ($ 110) at the beginning of the third you will have $ 121.
By maintaining the same profit conditions at the beginning of the fourth month you will get $ 133.10;
at the start of the fifth $ 146.10,
at the beginning of the sixth $ 161.00 and so on. In this way, after 5 months, a profit of $ 61 was gained instead of just $ 50 if the bankroll had been kept constant.
