Thanks for the evaluation mate. You've nailed it - I can now see those knees looking for a place to call home early on. I probably broke more at the ass on the early ones. I recall reminding myself to shove knees out about half way through the set.
On the width bit - I can't seem to stop stuffing around with foot position - but that definitely felt a smidge wide. I'll try it an inch or so in next time.
That's about as far in as my hands can get without more substantial shoulder pain. Shoulder ROM is still a work in progress.
Cheers!
