Betting 4 percent of your bankroll on any one game...and winning 10 units a month will increase your bankroll 4000% after 10 months. I calculated this by upping the wager at the end of each month to the new 4 percent from what the 4 percent of bankroll was the previous month.

Breaking that down further, to achieve that kind of an increase, we as bettors only have to win 2.5 units a week.

Say we had a mythical 10,000 dollars in our bankroll

We would be betting 400 dollars per game our first month.

If we won 10 units a month with a starting stake of 10,000

Month bankroll won balance at the end of the month

0 10,000 4,000 14,000
1 14,000 5,600 19,600
2 19,600 7,840 27,440
3 27,440 10,976 38,416
4 38,416 15,366.4 53,784.4
5 53,784.6 21,512.96 75,297.56
6 75,297.56 30,119.02 105,416.58
7 105,415.58 42,166.63 147.587.21
8 147,587.21 59,032.89 206,620.10
9 206,620.10 82,648.04 289,268.14
10 289,268.10 115,707.26 404,975.36

That's only less than a half unit a day....after two months our stake will almost have doubled...after 6 months it will have increased 10x, after 8 months our bankroll will have increased 20x and after 10 months, our bankroll will have increased to 40 times its initial value.
