Looking again at these details on the contest on
Post# of 1748
on the contest on the iBox:
Try it this way:
We need some separation between numbers (calls).
So let's separate by a whole number up/down the same digit;
.007 then .008/.006 -- .003 then .004/.002 etc
We are going to use a range-call of [ 10% }
A call wins if within a 10% range of the actual bottom:
105% times the bottom when above
to 95% times the bottom when below,
Two in the same range, the closest. then the 1st call, wins.
