kenchar,
I know, but I hope to get some leads to getting it right with interim info. such as yours, based on opinion and whatever else, and then if there is enough options to work with, i.e. field, runners,average prices etc, anything relatable, and hope to use some formula to mathematicaly get a spreadsheet and do the rest, and simply give a view, in color,showing the ranges,according to the info. entered.
Sounds complicated, but trust me...there is more to a particular theory, but need a benchmark first.
Might be a pie in the sky, but...
