I'm interested to know the best day to post as well.
I started to take notes about the success of my own personal submissions but not those of others.
I have observed that visitors from HN generally have a lower bounce rate at my site than do those who come from elsewhere.
My real objective in posting anything at HN is to get people two read my essays about my mental illness, the most significant of which are linked at the top of every page on my site. I don't want to just repeatedly post links to those essays, so I post other things, in hopes that those who read those other things, stick around to read about my mental illness.
You should add a link to your site in the "about" field of your HN profile. That way people reading your comments here might wander over to your site.
I did a quick search, but couldn't find your site, because your name is relatively common. E.g. there is a Professor of Mental Health Research named Michael Crawford at Imperial College London.
