Roy Johnson,
Since the groups themselves are getting shuffled as well, any 1 of the 100K numbers could end up in any position in the entire range. I had considered the selection of the groups each iteration to also be random but didn't think it was worth it. I didn't really think my position was correct.

I could have had the characterization of the problem wrong as I did come in on the tail end of it. My understanding was that you already had a list of 100K numbers and you needed to randomize the order. In this case, the numbers themselves don't matter just their positions. My process would be to apply the Fisher-Yates shuffle many times but on different scales. Sometimes using chunks of the list as though they were single elements and sometimes as though each chunk were the entire list.

Cheers - L~R
