The police let you follow them through their patterns, all well and good. Do they help each other with specific techniques to navigate better or is it just 'look, look, look' and trial and error after that?
Wouldn't it be great if there were some great cop cabal that was withholding information and denying us all greatness? Unfortunately there isn't.
ALL the motorcops I know(and that's mostly Idaho/Oregon) start their training the same way: MSF:BRC or TEAM OREGON BRT. That's their first step. They then go onto advanced "Motor Officer" training that pounds on the basics. I've not been to the CHP academy but I hear it's fabulous and they do loads of higher speed stuff. Several of the exercises they put me through the only coaching was "LOOK" and "Apex later" (coming in too tight on the inside pushes you wide at the exit of these things). I'm instructing a BRT with the Senior Idaho Motor Officer Trainer next month so I'll double check on what they work on mastering.
There's a great article here:

that details why there are competitions--to encourage practice.
I know you want there to be some kind of secret that you're not getting but ANYTHING you want to know about Motor Officer training is here
http://www.motorcops.com/index.asp either free or for a few bucks. Guys like Jerry Pallidino
http://www.ridelikeapro.com/ are making a living sharing this sort of info--yes, it's not free but who has the ability to dedicate their life to training and do it for free?
Do you want the real secret? The one that you're gonna hate? SPEED STABLIZES MOTORCYCLES. That's why motor officers have that basic attack speed they use. Know how I just go nutz because you feel you're sliding the rear? A. It's because you're not. B. You need to understand that speed actually stabilizes the motorcycle, the slower you go, the more wobbly you are. Cops attack patterns because they know this. I've NEVER seen a motor officer wash out the back or the front. The only times I've seen them fall (and I have it on tape) is when they GO TOO SLOW. You Gymkhana friends are hauling butt too! Watch the videos! I'm bank their average speed is somewhere north of 20mph. THAT'S why they wash out and lose the front or rear occassionally--they're coming in hard on the brakes from 30+.
That's why your 'slipping' fallacy is so counterproductive to your training. You're not slipping, yet by believing you are, you limit your speed, which limits stability, which makes you uncomfortable, which you misinterpret as slipping which makes you limit your speed, which limits stability, which makes you uncomfortable, which you misinterpret as slipping which makes you limit your speed, which limits stability, which makes you uncomfortable, which you misinterpret as slipping which makes you limit your speed...Feels like all the threads you've been in don't it? Round and round you go.
One last thought since we're on the subject of Motor Officers. Often, Motor Officers are referred to as "Motormen" it's a title of distinction and pride, one that is earned by taking the oath, wearing the badge and doing the job. I WOULD NEVER CONSIDER, OR REFER TO MYSELF AS A MOTORMAN UNLESS I HAD BEEN ONE AND HAD THE SPINE TO DO THE JOB. If someone were to refer to me as a Motorman I would suggest that was a lovely compliment and then correct them, reminding them that only trained, sworn officers have the right to that title.
