Why are the numbers of post important here? IMHO must be the quality of the posts, not the quantity, what should matter. You can have 1,000 posts and 900 of them can be crap. So, what does that say? On the other hand, you can maybe have a 100 and if 90% of them are quality posts you are doing good. I remember a law maker in my state. He had like 325 submitted projects at the end of one of his 4 year terms. 287 were congratulation resolutions, another 20 something were petitions to give some stupid awards and the rest law projects, most of them in tandem with other legislators. Was he a productive officer? You be the judge.
