I've been in the think tank for the last few days refining the core rules of the Philosopher Stone system. We hit a few losers on the trot (not that many at three) but this made me uneasy. The plain fact of the matter is based on simple stats: the more runners in a race the more chances a rogue horse could push our selection out of kilter. At a maximum of ten runners per race the system performs flawlessly, the only downside is you may have to wait a couple of days to find a decent bet. As ever, I err on the side of caution, and this will be reflected in the final product.

We've had seven more sign-ups for the Bismarx Bot lifetime license (www.bismarck.org.uk). The feedback has been great as more people are enjoying the benefits of letting "robo bot" hunt down the Betfair cash. I use it myself to great effect on the overnight races.
