I have no problem with trackdays and learning limits of adhesion etc, absolutely none. It does inspire confidence in road grip and your own cornering abilities but that comes with a price.
Unless you are intent on only using a bike on a track, it is very easy to transfer track habits onto the road. No, its not just the ex cop biker in me (although, probably does play some part
) but when you introduce traffic coming in the opposite direction, half the width of the available road, tar reinstatements, adverse camber, pedestrians, tractors and muck etc etc etc, thats where real world experience plays a more vital part.
You can be as fast as fck on the track but be a real liability to yourself and others on the real road.
And that is from riders who have done a basic one day bikesafe after doing regular trackdays, thinking they were invincible.
Ultimately, each to their own. 
I think we need to remember who this thread is aimed at, Tunnie is no stunt jocky afaict, without ever meeting him or seeing him ride.
I defy any individual to take nothing from any given training situation.
Tunnies chalenge imo, is to take it all in, pick what he needs and apply it correctly to his situation.
Your comments also remind me of a trackday at Oulton Park, local plod turned up to take part. 3 marked police bikes, a pan and a couple of beemers. They turned into the padock, all line asturn, feet up, and nearing the garages trying particularly hard to ride as slow as possible without taking a dab.
Apparently some derission was aired when told they would be in the novice group. Word spread throughout the paddock and pit wall was alot busier than normal when thier session started, you can imagine the reaction when the last of the group of 3 ran wide at turn 1 in his blind determination to perform a life saver before turning in.
Fair play though, they had a go, and found it, quote "eye opening", going by his tone and expression i'd say that was something of an understatement. Thier instructer said they took alot of possitives from it. Always worth a look at the other side of the coin...and ALWAYS with an open mind.
One of our number is a Police pursuit rider, has a wardrobe full of unmarked gear for under cover work, and gets a range of bikes to ride from Bkackbirds to Speed Tripples to RF900s following him highlighted several points of imorovement for me, living in Milton Keynes he was very good and accelerating into round abouts to avoid traffic with right if way, where normally you might pull up and stop and risk getting rammed from behind. Far safer.
