Big Bang Level EXP Curve

In fact, I'd like to see a graph of "how many regular mobs my level do I have to kill to advance to next level?", before and after. (Still doesn't take into account hits-to-kill and the like, but it'd nevertheless be far more meaningful than just a raw exp number).

I can only really contribute one data point, cause I'm lazy.

Obviously since the highest level mob is 13x, I'm gonna skip the "my level" part, and just pick the mob which is 153 post-BB and happens to be the highest level Holy target atm.
Before BB: 33600 Skelesaurs to level, 85k hp each = 2.8 billion damage
After BB: 19300 Skelesaurs to level, 260k hp each = 5 billion damage

Then there's the change in skills and base range.
Skill: 26% higher percentage on mob attacks (ACB is 37% higher, Holy is 8% lower)
Range: 49% higher average

So on the whole, my 2.8 billion damage (present) will become 5.25 billion damage (post-BB)

Meaning if the spawn and my killing efficiency is similar, 5% faster training? It should be a little better because right now I do a fair amount of overkill.
