You do this to prevent the inevitable tank-slapper that will occur if you keep the countersteer dialed in. Then, after being at dead center for an instant, you turn very slightly the other way (opposite the countersteer) in order to prevent the car from oversteering in the opposite direction.
At high speeds, all of this happens quickly in theory, and among experienced drovers is one smooth, indistinguishable process.

As both George and Finn (Peter?) ably show, the correction starts immediately with the slide. And as soon as the tires feel the input and start to regain traction the correction is removed. If you wait until after the slide stops, you are behind the car, and it will snap back the other way. That is how most of the spins to the inside occur, not because the correction was applied too late (although that happens a lot) but because it was not removed soon enough....

I completely agree with being ahead of the car, if not, pad things tend to happen. You really need to react instantly and that's where learning from the books ends (even though some of them can be very helpful), for that you need to spend time sliding, correcting and spinning. That's why I always recommend to go out and practice when it rains and also have suggested that our region would do skid pad practices (i.e. in Moroso you can get the skid pad wet).

The left hander at LRP is a place where you see to many spins because of this. People try to save it when what they could do is just open their hands and head straight towards the apex of the right hander coming out of the essess. Just give up the next turn, no need to try and get back on line.

ok here is my spin/drift that i didn't catch, I thought I had it until i didn't get the steering wheel back to center in time and ended up going off at LRP. tell me what you think. This happened this past weekend, it was a little cold around 40 degrees and windy. This happened at the end of big bend.

Down here, this happens routinely between 2 & 3, 4 & 5, 7 & 8, and 12 & 13 at TWS, and exiting Ricochet and Big Bend on the old MSR 1.7 course.

When are you reacting fast enough? When you correct for an impending spin before your instructor/passenger realizes it's happening.

For example the T17 on my video clip, looking from outside, the car was basically not going sideways at all, yet you see me correcting quite a bit (and you can hear the revs too).

In motocross we call similar thing "collarbone zig zag" because it often ends up driver flying over the handlebars and breaking his collarbone (have done it once...)

I downloaded it again and it is fine. What program are you using for viewing it? Maybe you should download the latest codec, you can download them here.
