We've gone over this many times. Just because a song's chart peak is higher than another song's chart peak, doesn't mean it's sold more copies. In order to figure that out, it would be next to impossible.
Are you saying that there is even the slightest chance that Under Pressure, which went to number one in the UK and top 30 in the US, sold less copies than a song that didn't make either chart, for even one week?

Oh and btw, I'd like to see the list of the "eleven songs" from the Sound & Vision tour setlist that weren't hits.
Well then, here's what you do. Look up the songs listed in Pegg's book, and compare them with the chart hits listed in Buckley's (or at Bassman's site). I'd have thought you could have figured that one out for yourself, but perhaps not.
