Philly Tide-

Yes, those formulas look fine- thank you.

I added a second line right after your formula that varies
the lookback number and the summation to be a variable
(using K1 and M1 below)
instead of a fixed number.

That way you can make a 2x2 table in Excel
(lookback values as a row and summation values a column)
and see the results of changing the variables.

Or use the solver add-in of Excel.
(If you have never used solver, take a few minutes to check it out.

Column E
=IF(B14=MAX(B14:B20),1,0) - (Philly Tide's)
=IF(B14=MAX(b14:OFFSET(B14,$K$1,0,1,1)),1,0) (using a variable)

Column F
=IF(C14=MIN(C14:C20),1,0)
=IF(C14=MAX(c14:OFFSET(C14,$K$1,0,1,1)),1,0)

Column G
=SUM(E14:E20)
=SUM(E14:OFFSET(E14,$M$1,0,1,1))

Column H
=SUM(F14:F20)
=SUM(F14:OFFSET(F14,$M$1,0,1,1))

and the oldest last and in this case that the data starts (say, April 2023).
