Hi Dingoboy,
To simply explain the Retirement Plan.
Say we want to make 1% profit on $1000 bank=$10

The objective is to win $10 plus all losses incurred in the process.
The divisor on a loosing sequence would be
1,2,3,4,5,6etc.

If say we strike a winner at 2/1=$3.00
We deduct 2 off the divisor ,this would make our last divisor of say 6 now becoming 4 then 5 then 6 after further losses,until such time we strike another winner or a series of winners which results us making our $10 profit.
Then start again.

The idea is to find out what your average odds of your last say 50 wins .
Lets say its 2/1 .
It`s recomended that you double this figure to create what your min divisor will be .
In this case it would be 4 ,we never reduce below 4 in this case ,regardless of what the odds may be, this is designed to protect the bank & to help ensure the progression is not too aggresive.

The recomended objective in this case seeing our min divisor is 4 ,would be to target 4% of bank & starting again as soon as we are say 1% or more in front ,this is important,this protects the bank from blowing out.

If min divisor is 4 the sequence would look like this .
Bet-Divisor
1----(4)
2----(4)
3----(4)
4----(4)
5----5
6----6
7----7 Win 2/1
8----5 Win 2/1
9----4 (Min. bet reached,) Win 2/1
10---4 Win 2/1 Small profit .Start again

We always start agin if in profit even if the total objective is not reached, this is important ,especially if betting with large amounts.

One modification I like to recomend is ,deduct the price from prvious divisor instead of the odds ,this makes it slightly more aggressive & easier to reach your target .
E.G. say we are on divisor 10 , we strike a $3.00 winner , I would deduct 3 instead of the original idea of odds being deducted say, 2 as in 2/1

You will note that your selection criteria has to be able to almost break even at level stakes to make this process work .
