i saw that you shot that wide open. i know that it is a must sometimes because of light, but seriously try f/7.1 or f/8 if possible when you're at 400mm. i wasn't happy with this lens when i first got it, but after i started shooting at f/7.1 i fell in love with it.
one thing to remember, while its by no means a cheap lens, it is like 1/10th of the cost as those other super telephotos, so shooting at smaller apertures is usually the only way to get shots that are as clear as its much more expensive big brothers.

No cheap lenses for me. I waited 2 years to put money together to get this lens rather than the 70-300...

Did you buy the lens used? you mentioned it was 5 years old. If its erratic when you test it with FoCal, thats a hint that it needs some service.
I really only use mine at or near 400mm, but being able to telescope to a short length is handy. I do not have any low light images with my 100-400mm L..

I have quite a few blog posts where I used the 100-400, but here is one that I think really shows off this lens's capabilities.
