Hi,

This bit is easy, it returns an array of True or false and remember that
true is the same as 1 and false is the same as 0. So this returns an array of
10 TRUE if every cell in the range is populated

SUMPRODUCT((A1:A10<"")

The next bit returns an array of numbers. If an item appears once in the
range it returns a 1. If the same tems appears 3 times it returns a 3

COUNTIF(A1:A10,A1:A10&""))

we then divide the 2 arrays and here's a shortened example of where a1 to A4
contained

a,a,b,b


TRUE TRUE TRUE TRUE
2 2 2 2

True/2= .5

sumproduct these and you get your answer of 2 which is four halfs added
togother.
