Final closing winning bet
$ 10.0 Fund Carryover
$1,356.8 Winning From MIDDLESBROUGH vs READING

$1,366.8 Final Fund (from $1,100 invested)

Stats Summary
Profit = $ 266.8 over $1,100 (24%)
Inactive weeks = 23 of 41 (56%)
Bets won = 12 of 48 (25%)

Looking at the chart, there was only 2 times over the 41 weeks where the returns is over investment. On paper, the 24% returns in less than a year (41 weeks) looks impressive but I rather call this a lucky sequence given the possible problems that goes wrong.

Big Problems with system
Assuming last bet of $640 lost
It will takes 13 months of $100 funding to allow for a next bet. An addicted gambler who can resist a 13 months of inactivity, should already quit. Assuming the next bet of $1,280 won, the ROI will be 7.9% for 93 weeks.

Chances of exponential bets
Given the bet won percentage of 25%, running a simulation test program of 10,000 runs, the maximum bet easily reached $17,179,869,183 which is a crazy amount. Even with a better win percentage of close to 50%, there is still a chance of getting a long stretch of losing streak.

Conclusion
This betting system is better left untouched.
