I was wondering if anyone had a good explaination why k=19249 generally has less pending tests than k=67607.

k=19249 always has ~1% less pending tests although the density for k=19249 is 20% greater than k=67607.

As an example the density for 19249 is very close to k=22699 only 2% smaller yet k=22699 always has roughly 16% more tests than both 19249 and 67607.

I just find it odd.
