Where did the #7-10 go?

The first result page says #1-6 showing

Ok, from what I regularly track, I found MSN search sometimes show only limited number of results on the first page. See below example(real one!)

1-6 of 1,472,852 containing blue widget(0.26 seconds)

11-19 of 1,472,852 containing blue widget(0.22 seconds)

So, #7-10 will never show up on the SERP!
Mine is on the second page now but I am wondering what will happen to pass the #7-10 position...

I'm getting 1-45, then 51-97

Maybe a little update going on since they also seem to have decided to double the amount of duplicate keyword subdomain trash, as if they weren't in bad enough shape already.
