Copy STDEV Conditional Formatting Across Multiple Ranges

See attached workbook. I have a set of conditional formatting rules applied to ROW 2. The rule is evaluating that single row and highlighting any values that are above or below 3 STDEV from the AVG. I would like to apply that same set of rules to the remaining rows such that each row is evaluated independently. For example; ROW 1 is evaluated as its own range and highlighted as such, ROW 2 is evaluated as its own range and highlighted as such, etc. Is there a way to do this efficiently?

The only way I can figure out to do it is by selecting the currently formatted row, clicking FORMAT PAINT and then individually painting the format row by row down the sheet. When selecting the formatted row and trying to paint the formatting across the entire range at one time, the rows are not evaluated independently, but instead as a single dataset ... not what I need.

Regarding my intent; each row in the sheet represents the monthly sales of a client and my intent is to quikcly and visually identify any outlier months for a given client.

I don't know what changes you are allowed to make. I changed your rules to be:

1) use a formula to decide.
2) edit formula to be something like =A2>AVERAGE($A2:$K2)+3*STDEV($A2:$K2) [for greater than 3sd above average. note the mix of relative and absolute references].
3) edit "applies to" field so that it covers the entire table.

That seems to work, though your sample data set does not seem to include any entries that this logic would highlight. I would suggest testing on some data sets that you know should trigger the CF and see if it is really working. (I changed to +/1 1*stdev, and added helper columns to calculate average+/-1sd for checking and it seems to work).

Would you be allowed to use a formula for conditional formatting?
