I hate to be a negative nancy about this but you should honestly consider a different topic. Regardless of how you go about it you will not be able to gather enough to data to hash the topic in any meaningful way. I mean many well funded research orgs have tried to tackle this topic and the conclusion is always the same, either they push a heavily biased conclusion or honestly admit there was not enough quality data to derive any real insight. Accounting for the low participation rate, and in this specific case highly dubious quality of responses I doubt you (or anyone for that matter) will be able to produce any more than a strongly worded opinion piece.
I think the members are warming up to CZlady. She seems legit. IMO she could probably gain better/ accurate responses if she started another pole. Maybe starting with 5 or less, 5-10, 10-15, 20+, 50+, and wife will hang me by my nads+.
