When I fill out the player survey, I face this question...
18. How many times did your character reach 0 Resonance Points remaining during this adventure? (Enter 0 if you started each day with 0 resonance.)
... and each time I don't know what to enter. I can't enter 0 because that means I started with 0 resonance. I've never run out of Resonance Points.
Should I enter -1?
Enter 0 if you never ran out also. The idea of that parenthetical is to indicate that starting with 0 means you never "run out" (the alternative would be that starting at 0 means you always run out every day).
