Give 'em a chance, Les. I think you're assuming too high a value of CPH (comments per hour).

Aside from the rate of CPH there's the minor problem that I've got no idea about BPM for the various tune types off the top of my head, and no immediate way of working them out!

However if you listen very carefully Les (I'm only over in Withington) you should be able to hear me playing them at what I consider a decent pace ...
