I found the same thing and decided to record it to prove the point.
I refreshed my RL ten times. Here is what I found:
200 names (10 refreshes)
70 unique names
1 name on all 10 lists
2 names 9/10 lists
4 names 6/10
4 names 5/10
24 names on 1/10
the name Alex: 2/10 lists
My IpH and my stats are both around 10M, so that may account for the limited pool. But it's wearisome seeing the same names over and over and over....
