Pull What
I understand what you are saying regarding low time students and PPLs but you do mix aircraft of differing speed and a slow 150 in front of a fast twin is a pain and usually means widening the downwind and overtaking, then extending to let him turn base before you.
You can almost guarantee the base will be too far and then the sod is all the way down final at 70 KTS.
Hence on a long final to a runway in faster machinery the thought of joint OH and making all those needless turns and speed differential decisions just to get back to where you already were makes the straight in far more appealing even though it makes for more constructive flying to not cut others up the same goes for downwind joins or even base joins from circuit height.
training aircraft can also be a pain as get 3 or 4 hammering out circuits all thinking they have right of way with instructors keeping them tight makes it impossible for others.
So please excuse pilots like me doing our own thing
