The point being, in IFR conditions as all commercial traffic is, a near miss is very very unlikely. I don't know of a private pilot that has not had a near miss. If you understand flight rules, you can easily see why this is too. I've had 100's of hours in IFR and can't say I've had a near miss while under it. During VFR, that is a different story.
So Skybird, without any further data, I'd have to conclude that the majority of those near misses reported by private pilots. No other way to explain it.
