Thank beton,
read that post, it seems the tests are a bit different to mine and not much there to say it's identical with formula in spreadsheet,
(automated - how times have changed !).

This one is loss chase, betting 0.33% of bank
The difference between the two is not only a name change, but betting is
0.5% of bank.

The 0.5% version has compound rules,
meaning, at the end of the day if the bank increased from 100 to 120, the next day it starts at 120, and so on till it doubles.
So at 200, remove 50% of profit, and new bank is 150, do the same till it doubles, 150 becomes 300, remove 50% of profit 150, 75, new bank then is 225
So far pocketed 125

Today, it starts at 1,178.65 units
2 rules:
1.Compounding daily, bet @ 0.33% of bank
2. Min odds: low within reason.
