Methinks an important question is raised here. What pays for a flight? Is it the poor old sods in the back, all x00 of them, or the few in J class (often travelling on free upgrades or as staff freebies). Some idiot in airline accounting a few years ago came up with the premise that business class is where the yield comes from. Don't think so, just that your systems have dodgy assumptions. Remember we vote with our feet guys !! Pack 'em in at your peril. VS, Y class can't even get my knees relaxed. Give us a break, we ain't stupid. The smart operator will be an all Y config with sensible legroom.
