I have a serie of about 10000 (or more) rows of numbers in several columns.
These numbers are from a log in a machine and there are lognumbers for every
miliseconds. Depending of how long one serie is (how many rows) there are
blocks with equal numbers. A long sequens make 32 equal blocks, a shorter one
16 and so on. I have made a test that takes out equal numbers and leave only
one left. If there are 32 blocks of equal numbers, the test deletes 31 of
them and leave the one in the middle left. This is to prevent to much data in
a workbook.

My problem is that my test depends on how many numbers are equal in every
block. I need to know if there is possible to count equal numbers from the
start of the column so I can give the result to the deleting test.
