Help extracting profit from Accumulator

Following on from Mark’s example on the 6-Jan I need some “baby steps” as I am struggling. Let me explain. The example given was 4 legs. All odds 1.5. and a £25 bet.
Leg 1: Lay £25. If it wins proceed to leg 2. If it loses, you have your £25 stake back and a 29.6% chance of getting the free bet.
Leg 2: Lay £37.50. If it wins proceed to leg 3. If it loses, you have your £25 stake back (37.50 = 25 + 12.50) and a 44.4% chance of getting the free bet.
Leg 3: Lay £56.25. If it wins proceed to final leg. If it loses, you have your £25 stake back (56.25 = 25 + 12.50 + 18.75) and a 66.7% chance of getting the free bet.
Leg 4: You’re now in a situation whereby if the leg loses you get the £25 free bet and if it wins you win £126.56 (25*1.5^4). Up to this point, you’ve invested 25 + 12.50 + 18.75 + 28.13 = £84.48.
Up to that point, I understand, however the example then goes onto explain this:
Let’s suppose you extract 80% of the free bet. Lay £71.04. This secures you £91.04 (£6.57 profit) in both cases: if it wins and if it loses.
I cannot see how the amount for £71.04 comes about?
Please can someone explain the method needed to do that?

Thank you in advance.

Thanks Dave. Where does the figure of £13.33 come from? 20/1.5 = £10. Cheers.

No deezer 20/1.5 = £13.33

20/2 = £10

Thanks Dave. Was getting confused with laying 20 @ 1.5 which would be 10

Like most i would like to try and get in to this. But at the moment i don’t have enough confidence or understanding from the all the posts on this topic.

So basically if i am reading this right. You have to place a 5 team accumulator at different times.

Because if you pick 5 teams all kick off at 3pm. How would you go about laying each team.

Yeah its called sequential laying. You want to ensure none of the legs of the acca overlap. You’ll need a spreadsheet which will tell you the optimum lay stake for each leg, depending on the outcome of the previous game. Also to maximise profits you’ll want to find games with low odds and close back/lay odds.

I can share a spreadsheet on here but may need to get Matt’s ok first, as it came from a rival mb site.
