Are these calculations correct?

I don't think these calculations are correct. For example, week 4 Steeelback (game 1 only): 7 kills, 0 deaths, 4 assist. (7 times 2) + (4 times 1.5)+(314 times 0.1)+2(for getting triple kill) = 53.4 points. How is he only getting 25.14 points? How is Yellowstar only getting 25.88 points: (1 times -0.5) + (16 times 1.5) + (38 times 0.1) + 2= 29.3 points. I don't know how they do the calculations but this seems a bit odd to me.

Side note: idk why but * wouldn't show up so I had to type in "times"
