From the same link above:

"Here's an endorsement of the calculator from Jd777 on the Betfair forum:

there's nothing wrong with the calculations - its just that they are too simple / one-dimensional for practical usage".

As is most of what has been said on this thread maybe [for starters, there is no such thing as automated betting software as has been suggested here that could be used to detect correct conditions and place bets for ANY type of betting system]?

The only system[s] that do work mentioned here have not been explained [Mark's method and maybe something Chrome was alluding too] and for probably good reason.
