That is a very interesting technique. I think the basic idea is something riders arrive at once they calm down, stop trying to scrape knee pucks in the twisties, etc. However, I wonder if trying to adhere to this too closely results in less smooth brake / throttle application, especially where the VP advises different behavior from The Pace.
Good question. I try to practice both--The Pace establishes attitude, and the VP helps de-mystify unfamiliar turns. I don't think they conflict and, in fact, see them as complementary. Nick writes: "The Pace decreases your reliance on the throttle and brakes, the two easiest controls to abuse, and hones your ability to judge cornering speed, which is the most thrilling aspect of performance street riding." And judging cornering speed is what the VP helps with.
The VP probably results in faster times through a given series of turns, as you're accelerating and decelerating to match curves within their visible limits. The Pace, on the other hand, uses throttle control instead of brakes to control entry speed, resulting in shallower deltas. Given a constant radius turn, The Pace seems like it would arrive at the minimum speed through the curve as the entry speed, whereas strict adherence to VP enters the curve at a higher speed, and advises trail braking as the VP gets closer... then a correspondingly increased application of throttle as you can see more through the turn and the VP fades into the distance.
The VP technique doesn't require use of brakes. Deceleration as you close in on the VP can be achieved just by rolling off the gas, depending on speed reached on the preceding straight. And that's personal preference--which, for me, is usually governed by The Pace.
The two coincide well on the point of minimum speed and turn-in. The Pace encourages slowing while upright, quick turn-in, and roll-on through the turn. Nick again: "Steer your bike forcefully but smoothly to minimize the transition time; don’t hammer it down because the chassis will bobble slightly as it settles, possibly carrying you off line. Since you haven’t charged in on the brakes, you can get the throttle on early, before the apex, which balances and settles your bike for the drive out."
It may seem that a speed profile dictated by the VP would have you trailing either the throttle or brake deep into the turn, but that's not how it works out. In fact, the transition from deceleration as you close in on the VP, to steady throttle when the VP is at constant distance, happens
before you reach the constant radius segment of the turn. You
see the constant radius before you get there. That's shown in the photo sequence at points 5 and 6. From those points, distance to the VP doesn't seem to change much. But from the marked-up aerial view, you can see that you're still 20-30 yards away from the constant radius segment. Thus, that visual cue from the VP can be used for steering input and roll-on, and it will happen in just about the place you'd want it to happen for riding at The Pace.
