delete misfire on 2.jpg That shows Cylinder 2 as bad, looking through the frames it does misfire often but not all the time. delete good on 2.jpg It could be shown better if you were to take that capture again with more time across the screen - showing 6 injection events across the screen not just 2.

Hope this what you need.
I will be happy if you can explain to me how you get the formula to the math channel.
