Row 1 above would count 4 - Column 1 matches column 3 within 10 and Column 4 matches 5
Each column represents Degrees 0 to 360 (around 40,000 records)
It is a quality assurance metadata for a sorting column. How often do these rotations come within 10 degrees of each other?
Note: I realize that 0 degrees (359 degrees to 3 degrees) is tough. There is a Master rotation that is always at 0 - not shown.
For those close to 0 degrees - I have already designed a custom column for that.

The idea is to find when those rotations not close to 0 degrees are within sync with each other.

Count of 3 first 3 columns - the key is not to double count.

Basically, there is a set Range (columns) of 5 columns with degrees (0 to 360).
From there when a column is within 10 degrees of any other column - add 1 to the count.
If there is a formula, great. I am not opposed to creating a VBA formula if necessary.
