HELP with the maths - Lay Away team sequence

[sfarad]

Hi guys,

I am struggling with the maths to build a strategy of the following specs:

1) Pick 15 specific matches every week. The odds usually are from 2.00 - 3.5 for the away team  

2) Lay the away team.

Now, with my historic data of 3 years the highest number of matches in which the away teams won was  8 out of the 15. Normally it's 3-7 away wins out of the 15. THIS IS why I want this to happen.

Here comes the problem. I am thinking of building a progressive strategy in which in case I lose a match, I double or bet 1.5x  BUT the 15 games I pick do not occur in a sequence. Normally 3-4 matches occur at the same time... So I could have 4-5 groups of matches until the 15th game is over.

Is there any possible way to build a strategy to succeed with this strategy?

This is effectively a martingale system and is doomed to failure long term. Doubling up on expectancy is a long term loser. Classic examples of this are when people see 5 or 6 reds on the bounce and bet black in casinos. I once saw 23 reds on the bounce and the double up bet from 6 to 23 starting at £10 is around £500k.

You will win with martingale for a bit, but when you lose, you'll lose everything you gained previously because the multiple bet becomes so big - bigger than your bank.
