I have no idea what the average time is, but it doesn't really matter. Some people post a lot. The most active members shot through 300 posts to Enthusiast in the first few weeks. Other's only post a few times a year, have been here for years, and not made Enthusiast.
If you are enjoying the forum then you are posting exactly the right amount.
Most of us don't pay much attention to the titles. Well, except the very first one; because sometimes you want to adjust your answers to those who have not been on the forum long enough to know the community and rules.
Anyway, I suppose an Admin might be able to coax some kind of statistic out of the forum's history, but I suspect they won't. It would only encourage the idea that title are a competition. Posting for the sake of posting isn't something any of us wan't to encourage.
That being said, I know how a numbers question can eat at you. If I really wanted some kind of measure I would start recording the Join Date and post count of active members. A little work in a spreadsheet would give you some sort of number. Best to consider it a just for fun thing though. There would be too many unknowns to draw any serious conclusions.
Oh wow! Very well said.
