Max amount of kills by certain level?

[Bunnyshoota]

What is the maximum amount of kills achievable at, say leveling 1-50.

Assuming:
1. No bosses
2. Least optimal exp/enemy ratio (for example, running ao1 at 42 will result in less exp/kill than running ao1 at 33.)
3. No skipping ahead to next campaign until exp is no longer obtainable at the previous one (running ao1 until 42-43, then going to ao2)
4. without using plat exp elixir
5. No exp elixirs


Thanks
