Hi experts,

This is for calculation of bowling averages.

There is a variable length list of numbers in a row (score history of a
bowler, new scores appended to the end).

What are the functions to find:

1. the average of the last 21 numbers
2. Filter the scores that were above 150, then calculate the average of the
last 21 of the filtered list

Million thanks!!

If your scores are in column A then:

=AVERAGE(OFFSET(A1,MATCH(2,1/(A1:A65535<>0))-1,,-21))

This is an array formula and must be entered with a CNTRL-SHFT-ENTER

The same type of formula can be used on a filtered list.
