Another method for fine tuning AF

Interesting - I might try that.
The method I've used with the 55-300mm is to take lots of shots of a distant non-moving subject at each AF setting, average the RAW (or JPEG) file sizes for each AF setting and then pick the setting that gives you the biggest file size - and hence the most detail.
How do others do this?

That's more or less what I do. The key is the 'distant object'. I also pixel-peep once I get roughly the right setting. It always amazes me what lengths people go to with their charts and whatnot. Once you've got the infinity setting right then the camera should read the near distance corrections from the lens. Except when you have a Sigma lens.
