and how much it was simply
Either go with the repeating idea from "How much of it" and change the above to "and how much of it was..." or cut it out like reading through from the start "and how much was..."
A moment of introspection brought the impact our relationship to bear.
Add "of" after "impact"
then made adjustments to specific players in the raid to give us the best chance of knocking at least one of the four attacks off the to-do list.
Sounds better as "and made adjustments..."
