I know this is common on full sus bikes and those badly set up with short outer runs but this is on my Kaffenback with plenty of outer between levers and frame and from the frame to rear mech. Could the ghost shifts be a sign of worn ratchet in the STI levers? What confuses me is that sometimes it will shift one way, from a larger to smaller sprocket, other times from small to a larger sprocket. The STIs are approx 4 years old and untouched by me, tonight I've given it a short spray of degreaser and will lube with GT85 in the morning.

Done that already before I built it as I secured the bolts with a dab of threadlock. Outers are running free on the inners. What makes me think the gear levers are at fault is that it's only the middle 3 gears it happens in.
