OK following Karslruhe U19 game bank now stands at £167.88.
Every time I reach a 20% increase in my bank I withdraw 10% of that 20% increase to give an overall increase in my bank.
I have been through this barrier twice more since I last withdrew so I am withdrawing £12.10 and £13.31 to give a total withdrawal of £25.41.
My bank therfore now stands at £142.47.
My next 20% target is £175.70 at which point I will withdraw £14.65.
Hope this makes some sense.
