Hello,
David B sight read one note at a time. Beyond that the skill is nonexistent.
Same here. I study pieces, annotate octave numbers and note names and everything else I guess I should know (all on copies of the original pages) in pencil.
Then, start learning and memorizing the piece until I get the hang of it. It feels free and airy and more expressive to 'just' play from memory and muscle memory without anything in front of my nose.
Cheers and happy lines, dots and whatnot,
