Hi @The-Magic-Sword I hope you didn't forget about the very first sentence of the thread:
(That Wizards can "outpace the DPR" of a warrior in the round they cast Fireball is not under debate)
5th level is when you get your first 3rd level slots, with which you can potentially cast fireball (among others), the level 5 Wizard I drafted in Pathbuilder just now to check has two third level slots, and can restore one of them using their universalist feature. It would be possible to use spell blending to get more but let's not eke out every single advantage.
All my math pertains to sixth level characters, because that is the level my players are currently at when the encounter I shared my experience of happened and then deconstructed it, using their Save DCs, and spells.
That falls in the 5 to 7 range, but the math is pretty tight and scales linearly so the main limition below 5 is the number of damaging AOE 2nd level spells that exist in total.
I'm also uncertain as to how you would justify it's exclusion, since fights in Pathfinder aren't that many rounds in total so dealing a massive chunk to the encounter right off is more valuable than the theoretical sustained DPR of swinging at the same target all day.
