Going full circle - the power of compounding

I was reading Steve's posts here and reading about his struggles with discipline, rash decisions, mindset and all the stuff most bloggers with this particular interest seem to struggle with. I've got to admire his stoical approach and belief that he will come good if he keeps at it and learns as he goes. This recent post caught my eye in particular as it echoes the way that I started this blog way back in the mists of 2010...

Lazy trader here, I haven't really push the boat out in terms of trying to make my bank any bigger, I reckon if I carried on at this rate I would probably hit the betfair upper premium charge ceiling of £250,000 in about five years worth of compounding, so it would be worth it in the end, but apart from that I'm doing OK and it allows me more time to get my college work done in the evening.

I think Steve is working to a compounding rate of 1% to come to that conclusion. For his benefit, and for a bit of fun, I need to tell him that if he were able to up his rate to 2.5% per day (and get all trades matched, take care of commission and not make any withdrawals) that he need only wait until 17th February 2013 before he starts paying the SPC he seems to have set as a target.

Here's the proof:

It doesn't look too hard if you glance at the top image, but how exactly you go about getting the 6.25 large you need on 17/2/13 might be a bit harder to compute....but fortunately I have a plan...

 You back 0-0 in a big prem game with an hour to go before kick off at 12 for £143506. Laying it off at 11.5 five minutes later would bag a green of £6239.39. So you just need one such game per day. And pray you get both the back and the lay matched and don't have to take it in play - that might be sweaty palm time.

Fortunately, 17th February 2013 falls on a Sunday so big liquidity matches should abound. But a cold, damp Monday night might only offer 3rd Division Argentinian fare with less than £6k matched. Hmmmm ... back to the drawing board then!
