is that your own calculation or who has done it?
Yes, my calculation.
you got the idea from caspar's posts?
I've been searching these threads, where is talked about formulas, but actually found only one; but none with this "3" or "2/6".
Anyway in the sheets have been 3 categories of accounts ... is that the thing, to which your formulas are based on?
Otherwise are too many double units outstanding. That is not fair!
