Yeah, I'm not really sure why there's no update until monday, it SHOULD be all hands on deck but I guess there's some interruption over the weekend. But yeah all the people doing ballot counting will be doing it over the weekend.
We still get new ballots in about 4-5 days after election, so having all the votes counted right away just isn't possible. Mail takes time. Speeding up the process would cost a lot more money for no real benefit because the elections aren't certified for a while anyway.
