Those look like recalculaion times. I get similar results when I test the
recalculation time.

I tested the *initial* calculation times.

Array had the lowest average, tied with Index for the lowest min, and was
the most consistent, with the lowest range.
Sumproduct had the highest average, the highest max and was the least
consistent, with the largest range.

Just as a point of information, can anyone out there with access to Fast
Excel or other similar software determine which of these formulas would
be
faster and less resource intensive?

Say you size them to 7,000 rows.

Gary's Sumproduct:
=SUMPRODUCT(MAX((A1:A7000="north")*(B1:B7000="high ")*C1:C7000))

Tm's Index:
=MAX(INDEX((A1:A7000="north")*(B1:B7000="high")*C1 :C7000,0))

OR, a standard *array* entered formula:
=MAX((A1:A7000="north")*(B1:B7000="high")*C1:C7000 )

Hi

I have a spreadsheet that contains text and time information such as
below:
a b c
1 north high 5:21
2 south low 6:42
3 north low 7:14
4 north high 3:56
5 east low 2:14
6 north low 2:02
7 north high 2:37
All of the information in the spreadsheet is the result of formulas
from
other data (in other sheets).
I need a formula that will provide the maximum time (in Col C) in a row
where (for example) the Col A is "north" and Col B is "high".
Any help would be greatly appreciated.
Thanks.
