How long does it take 16.7.2.11 to be pushed out?

I have three systems with NIS 09 running XP Pro SP3 32b.  My laptop picked up the 16.7.2.11 almost immediately.  However, my two desktops still haven't received it.  Automatic Live Update has been working properly.

 

Given that it has been a week now since the patch was announced for gradual deployment, I am just wondering if my systems are functioning properly?

 

Thanks.
