Whilst I won't pretend to understand what your charts mean I think I know what you're trying to do, and I believe it will be a rollercoaster ride.
There will be races where you may have only the one winner ie the horse that despite its rank (wherever that may be) will be over the assessed price and not laid, and if it's right in the market the others will all be losers. Similarly I can see races where you only lay half the field.

Good luck with it but I can only stress (again & again & again) that bookies make their profits from the short end of the market, and every race is totally independent from every other race.
