this whole conversation is pointless

Bingo!

I mean, I'm sorry to sound harsh, but it really is pointless, because it can vary so much just because of the factors already mentioned and others besides, a few of which are outside our immediate control.

It's one thing to compare notes because you're interested in it as theory, but there are no practical takeaways without knowledge of niche, target audience, traffic, ad placement.. (I could go on) I see variances between 1% and 23% just on my own sites. All you can do is monitor your own and see if it rises.
