HI;

You don't mention the number of rows involved (all the same number, but what number?). The simple example would be if you had 10 amps and only loaed 8 roes -- it would be skewed. Less expected, but still kind of obvious: Load 105 rows (again, to 10 amps) and the fivve amps with an extra row will have 10% mroe than the other 5 amps = skewed again.

I guess the first question to ask is whether the number of rows is a multiple of the number of amps? If so, it would seem that there should be now skewing....
