You are very close to where you need to be, but I agree, I would richen the idle just a tiny little bit more for better overall manners and a more reliable idle. I am really talking a little bit here; like the width of a screw driver blade, no more. It's just a fact of life with these engines that the idle has to be a little richer than an ideal, smooth perfect setting for best ALL around handling and performance. You are on the ragged edge of being too lean at idle right now and it could eventually cause an idle hang problem or dead sticks.
