TVMP 3 scoring

In all the videos I've seen or murder party 3 the scoring has just confuses me

Like in 2 correct answers worth 1k a kill bonus worth 500 and some other things here are there like maths and rules being 25 for each one right

But 3 doesn't make sense to me at all I do like the losing thread instead of being a ghost it allows someone to get the first question wrong but still be the leader in the escape. Beside that I don't understand the numbers
