On reflection, I should have named this thread, 'Know your limitations, and work within them'.

TO, I am developing new bottable systems and set to test shortly. My main worksheet is an excel 'blackbox', following on from my create a 'blackbox' thread. I break all my systems up into variants to suit no. of runners amongst other variables. The calculations of each variant appear in the top row, that's frozen, so it can be viewed at all times

I call it my 'dashboard'. As I enter data on the current prices of potential selections these cells across the top row update and show me the % chance of winning (as in first past the post). As I'm a Layer, I'm looking for variants with the best optimised chance of losing.

So to answer both you and Michal, my methods are partly automated.
