ALL: Trail braking is an advanced skill bordering on art. My street noobs at Grattan Raceway get told not to trail brake and concentrate their efforts on more important stuff like threshhold braking and picking a good turn-in point and then getting the bike down to full lean in one quick motion. Stuff like that. Trail braking requires smoothness which requires time. It requires a light, to the point of delicacy, touch on the bars and controls. I wouldn't bother talking trail braking to a rider who as yet cannot take one hand, if not both hands, off the bars while cornering at full lean.
In the book "How To Toilet Train Your Child In 24 Hours" there is a 3 step test to see if the kid is even ready for the effort. I wish that Nick and some of the other top know-it-alls would come up with some tests to see if riders are ready for the so-called advanced stuff?
Recently, Cycle World, Aug. 2012. p. 49 shows a rider's blistered hands from a long day at the track. To my way of thinking, if a rider blisters his hands, something(s) is severely amiss? Blisters are are not a sign of delicate touch on the bars.
The "Upper Half Of The Motorcycle" discusses how much braking is still available when the bike is at full lean.
You're never not ready for advanced skills, at least to be introduced to the concepts. A good coach can discuss the concepts with you and still have you more focused on what actually needs to happen.

Allot of track day schools dumb stuff down, you get told the wrong thing to prevent bad things from happening. Look at the prevalence of late apex's. The "school line" is almost always late apex _everything_ because the consequences of fucking up a late apex aren't nearly as bad as being early. This dumbing down is lowest common demoniator training. It keeps everything nice and safe and relatively slow, but holds back fast learners to an extent, because you learn the wrong way then learn the right way. The question always remains if you'd have survived learning the right way from the very beginning.

As to blisters... Well there's another one of those track day lies no?
All control inputs should be as _smooth_ as possible says the instructor to the n00bs. Well define smooth... I can turn so smoothly you'll never feel the G's building up, it's going to be slow around the track.

Really when you say smooth you mean bring the tires to maximum traction without exceeding it as quickly as possible which is going to require a progressive application of brakes, throttle and steering (and most likely an overlap of all 3). But when done by a racer it would not feel smooth it's going to feel very abrubt because the brakes are going to come on to maximum very quickly, and then they're going to feather off as lateral acceleration replaces the decreasing brakes, but it won't feel in your classical sense "smooth" to anyone but the operator or the guy looking at the data acquisition that see's the G-force line shoot to 1g deceleration and then without ever coming back to the middle goes directly to 1g lateral acceleration and then with out ever coming back to the middle goes to .3g of acceleration.

When you're doing it right on a fast bike you're defiantly hanging on as you move from side to side while hard on the throttle.
