A few points.... It could be because:
The LO (or whomever they designate) simply didnt do it....(not good)....
They could be away on vacation, or someone out sick....
They could have done it, and believed they sent the update in to Nationals, but it didn't take for whatever reason (this happened here last week-I called and asked, she told me she was sure she had sent it, but re-sent it while I was on the phone, it was updated in less than 15 minutes......)
There are probably a dozen other possible scenarios. Or more.
Hopefully, for you, this isn't a recurring situation. Realize that your LO likely has many other divisions that they are keeping track of, and occasionally "stuff happens."Perhaps that's all this is. Again, I hope so, for your sake. I, too, enjoy checking out the stats each week.
BTW, LO's are not supposed to publish stats on their own web sites any more, since the National site rolled out. They can maintain them for announcements, and calendars of events, and results of tourneys, and everything else you might want to do on a website, but all stats have to be seen on the National site.
