Then i guess it is splitable into active CoO and passive CoO. His passive CoO seems not thaaat good (by taking your examples), but his active is shown as not that bad, like i said with Hodys attacks.
Also his Focus is, i guess, the CoA-Haki, while Sanjis is CoOs.
I just wanted to say, his CoO seems to be enough to negate the negative effect of missing an eye, then your examples where also from spots where his second eye wouldnt helped him.
