Most Active User List Help please

I realise this is not important, but I just find it weird that since joining in May 2009 I have never, ever appeared on the Most Active User list.

I asked about this once and members told me it depends on what times of the day you post. I don't think this would apply in this case.

For example, yesterday I posted 20+ times and today I have posted 40+ times.

Has anyone any ideas? I am getting paranoid. Please keep it polite LOL

Kind regards Jane.
