I don't understand what you're trying to get at. Any damage output stat will also increase damage done by bursts. Any burst damage done will also increase the damage of the full burst bonus. As such, any calculations like this would directly apply to other damage skills just as well.

Putting values into my calc, Wind team running at 148% Assault against Thunder, for damage/t 30 Exceed = 30 Crit = 17 Assault. All numbers include (small) base. If you're looking at burst damage only (which I guess you can argue for as peak damages are a thing for skipping phases), 30 Exceed = 54 Crit = 32 Assault. Vigor absolutely crushes these stats at 100% HP at skill level 1 (thanks to base), but again, Vigor has the problems of unavailability and unreliability.
