This too has been explained multiple times - and its very simple to figure
It started with them believing the bad polling -- they really thought there would be a "blue wave" - LOL
They did not realize the polls were wrong until 10pm or 11pm on election night.
When reality did hit, it hit like a ton of bricks -- the polls were total BS
Trump lead by 10s of thousands of votes, even 100s of thousands in some states
They went into panic mode
They had to scramble to produce more ballots than even their worst estimation
So they shut the count down and sent the observers home for the night
Meanwhile they began filling out blank ballots in the cabs of trucks
They were in a hurry
If they only needed to fill out 10 or 20 or even a hundred ballots, they had plenty of time to fill out the down ballots.
But that was not the case. They had to invent way more votes than that - they needed 10s of thousands of new votes - so no time for the down ballot
They needed so many votes it took them hours to produce, even without the down ballots
And they then began dumping them in the dark of night, when no one else was still around
I can even give you the state and times of several of the big vote dumps
IL + 500k at 3:36 am
WI 140k at 3:42 am
MA + 100k at 3:42 am
MN + 200k at 5:30 am
GA + 100k at 6:30 am
MI + 130k at 6:31 am
PA, AZ and NV fit in there somewhere too, but I cant find those now
It's so simple to explain even a troll can see it -- they had a lot of ballots to fill out and not much time to do it. I have no doubt even you can see this too, its just that you will never admit it. But that's ok. Because, no one here ever expects you to be 100% honest. It's not how you roll. Indeed, no one expects anything from you except more trolling. You exist, even wallow, in the stigma of low expectations that you have created for yourself.
