Why did I start with 138 rep here instead of 101?

Question

Looking at other user's, I see that meta.webapps... rep isn't shared with webapps... since not everyone's rep is in synch. What's going on here?

Answer 1

I just saw Robert's answer to this question. That answer, along with his comment to his own answer, answers this question. Rep is shared with the "parent" site, but it's only updated every hour, so it may get out of synch.
