Yeah, I scope about 25% of the time. Auto is good, but like ret, its just a rough tool. If you are good at ret, you can trust yourself over the Auto.
I personally found our Auto is not accurate past -4D, so if the patient is high, I ret anyway.
If you are looking for a way out of learning this skill... sorry! It is tough for some people to get, but its imperative you know it!
My problem learning it was I did not have my working distance down. I thought I was right at 1.5D away (66cm) when I was actually closer. I now use 1.75D as my WD and it works perfectly. Dead on.
Morale of the story: practice!
Good luck!
