We did a drill sequence last week, which was "slalom" -> "aggressive slalom" -> "aggressive slalom to hyperglide". Aggresive slalom meant the skater would push on the outside skate. As you'd slow down, the stroke would become a back push -- people would have to stop, take a few strides and start again, because they could not move the back skate up and keep "slaloming".
Those that did not stop were "noisy" -- the wheels would scrub on the track. This scrub was a sign that you were doing it "right" -- at least pushing hard enough to overpower the frictional interface. Which makes wheel scrub inefficient -- the forces are not propelling you anymore -- they are making noise.
To combat wheel scrub, you had to ensure that the pressure that you generated was more evenly distributed over all the wheels, not ONLY on the heels.
Also to keep the pushing skate up with your body, you had to do a "waist steering" sort of move -- drive the outside hip forwards during the push. You had to turn the skate slightly inwards prior to full extension for recovery. Turning the skate inwards and driving the hip forwards meant you could do this drill silently, and maintain a much wider range of speeds.
From this laymans analysis, moving the frames ahead would make the recovery pivot that happens near the end of the stroke easier -- perhaps by as simple a mechanism as overpowering the rear wheels on the last 1% of the stroke?
