Raising money by half instead of doubling gets you smaller profits but the up side is that after you have lost 10 bets in a row with doubling you have to make 25600$ bet and with raising them by 1.5 you have to make just 1950$ bet, starting bet 50$ in both cases.
A starting bet of $50 is too high and I would never play around with a Martingale system with such stakes. I have placed bets in the past of up to €100 on singles, but that was on matches I was very comfortable betting on for various reasons.
One of the challenge/flaws I may find with your experiment is that, most time the selected team plays perfectly at home, most teams have many wins and less draws at home ground unlike the opposite, looking at the match history of a club, you'll find out they probably have good outcomes at home ground,
That is usually the case with the top teams in each division. As you move further down the table, the home venue isn't such a deciding factor. That is why you shouldn't pick teams that are too high up on the table.
Roda's last 5 home games:
2 wins, 2 losses, and 1 draw.
Paris' last 5 home games:
3 wins and 2 draws.
I know your aim is about high odds right? So which is necessary, high odds or good outcomes? I prefer good results.
You can't make a profit if your winning odds aren't above 2.00. So the odds are of the outmost importance. The aim is to make a profit every time your selected outcome wins.
Consider this:
You bet $3 and your lose.
Next round, you bet $6 and you lose again.
In the third round you have to bet 12$. But if that bet is on a 1.50 odds, you wouldn't have made any profits. You would have a loss of $-3.
If the odds on your 3rd match were 3.00 for example, you would have made a +$15 profit.
After all, we are talking $3 to start with.
It doesn't look like much, but notice in the results how that stake of $3 can quickly become a stake of over $700 if you your have multiple losing rounds in a row.
