A true anaerobic effort doesn't go much further than 2 minutes, maybe 2.5 if you are really anaerobically gifted. That you are conflating a 4 min effort to be anaerobic suggests that you have no idea what anaerobic means. FYI, a 4.5 min effort at 120%+ is still, by definition, an aerobic effort; it's known as individual pursuit in some circles.
Last year in one crit i did 110% AP (115% NP) for the last 10 minutes to get in the break that stayed away in a very tough crit. The first 3.3 min of the move was at 123%. Guess what, that's still an aerobic effort because had it been truly anaerobic, i'd have blown the gasket by the 4th minute and probably would have been too shattered to even latch onto the field.
I think your definition of anaerobic efforts is a little off. Basically any effort over threshold (FTP, CP etc) has an anaerobic component. The amount of power over threshold for a given duration is a function of your anaerobic work capacity (AWC). Monod & Sherrer came up with the original equation: P = CP + AWC/T defining the maximum power P you can put out for a time T.
