Lots of interesting points in the link but it doesn't hide the biggest cause of slow play.........inconsiderate people.
You should walk between shots, not amble.
You should be ready to play when it's your turn (glove on, distance measured, club selected etc)
You should leave your bag at the correct side of the green.
You should line up your putt when everyone else is doing the same, not wait till it's your turn
You should NOT think it's OK to play slowly as long as you call groups through, that causes bottlenecks!
You are of course right , I just adjust my pace nowadays to the group in front
