This is great - thank you. One thing I would mention (and not being critical here) is that your spreadsheet doesn't take into account armour builds. For example The First Curse can actually 2 crit shot low armour builds (TTK of 0.5 seconds) and 3 body shot. Maybe something to incorporate into it if you are thinking of building on it? There is something similar on Reddit (although I don't think it's been updated since the spring update) that includes this sort of detail.
