Chiming in with what Rich said above, with a more specific example: if the question you're trying to answer is "how long will it take me, the average climber, to get to 5.12?" you won't get the answer from these data.

One reason for that (among many) is that as a piddling 5.8 leader who manages a few 5.9s and maybe a 5.10 every now & then, I ruled myself out of eligibility for answering this poll. Clearly, you're not interested in me. So your sample won't include a lot of people like me, and will not answer the question you're asking.

On the other hand, if you're asking "how long has the average 5.12 leader been climbing?", you've got other sources of bias, including the large grain of salt with which you should take the responses here, the variance between grading at different areas, and the likely inverse relationship between peak climbing ability and time at a keyboard/internet.
