But you didn't give an example. You just said it was so.

While I agree that Wendy is also growing very well. I don't mean the new spells she learned, but rather how much she can heal without falling over exhausted, like she did in the Nirvana arc.

But she is a Dragon Slayer and those seem to play in a different league from normal people. Besides even if Wendy is growing even faster, that still leaves Lucy's growth rate quite far above average.
