Shagpile is on the money. The issue is not whether you are being pushed and going faster. The issue is whether the person doing the pushing is doing it in an intelligent way. Do they have the skills and capacity to determine whether you are ahead of or behind the aircraft? Do they know how to manage your workload so you get the maximum value for your hours?
I get far more out of flight reviews when I'm sweating and on the edge of my capability than when I'm loafing along. I get far more out of circuits on a bush strip at 300 feet than I do out of trundling around a wide circuit - 5 or 6 an hour.
I'm all for a bit of intelligent speed. I'm not much interested in clowns who can't understand where the mug (me) in the left hand seat is up to.
