Sounds like lots of hormones going to waste on this thread,
There are some very experienced drivers among the S2k group, and I have a lot of time and respect for their driving.
Oh you Driving Gods!!!

Oh dear gents. It sounded nothing like the relaxed atmosphere at anglesey. If anyone seems upset or short changed after a Bat event then it must be because of some exceptional event since out of all the track days I've been to, i have never been as impressed with how professional and fair it's been run as by Jonny and his team.
From the write i am glad to have missed it due to a poorly clutch.
Can't ewait for the spring S2k trackday, any ideas on where yet? Rockingham or somewhere new?

Unfortunately, when we finally did get on track (and not behind the instructor's car) everyone wanted to be on track at the same time and hence it was very busy. I for one was held up by a number of cars that didn't move out of the way, the yellow radical that simon jumped out of the way of being one, but the bulk of them just being due to queues.
I know that i didn't get one clear lap all day without being held up by traffic, but that's just the nature of a busy day.
This problem actually reinforces my view that we're better off paying a slight premium and using bookatrack as opposed to using some of the cheaper trackday providers.
Bookatrack days are (frost and general weather anomalies excluded) much quieter on the track itself as they book less cars per day (hence the guarantee of no queues) and you just don't get the traffic problems that we saw on sunday.
The next day will probably be Rockingham in April/May.
I'll obviously be doing my best to avoid clashes with any other S2ki events so that we don't have to have S2ki'ers choosing between a trackday and a drinking session

I think i nearly offended Carrie when i said within earshot that you could tell who'd been out the night before by the smell
I was of course referring to the alcohol fumes they were giving off

just a shame that the weather let us down so badly.
Hopefully see you at the next one where we can have a full day's running!
Since the next one you guys will arrange is for April/May I'll see if I can get out to Brands in Feb/March time
I'm keen to do 5 track days or so next year

While we have a short break in the flaming sessions I thought I'd chuck up some screenshots for the datalogger for the nerd^H^H^H^H...analytical types amongst us.
THis is a screen shot from data on a session later in the day.
I've overlaid the data with another trace I found on the web from a session at Donington from a guy in an M3 CSL just to provide some sort of comparison.
What it clearly shows is I'm stopping accelerating going into craners (That's where the two cross-eyes are on the graph). I've got reasonable mid corner speed in old hairpin and good drive out but I think the radius on the corner can be made larger. It looks like I might have been backing off slightly through the sweeping lefthander (where the bluebird is). Corner speed through Mcleans looks quite good but I'm slowing far too much for Coppice and need more corner speed although the drive out looks ok (the sun in the eyes was tricky though). Redgate could be done better and ona day where there is no ice on the left at the entrance that might be more doable. The speed on the straights and braking at the end could have been higher and harder but they're easier to do once the corners have been sussed.
The graph in the top right shows estimated power Vs RPM and the verdict is around 205HP at the wheels (241HP at flywheel for 85% efficiency in drivetrain). It's a corrected figure but I'm sure the cold weather helped here. Peak cornering g was about 1.15 in the old hairpin (Tyres are worn T1-R's on the front and half worn RE050 MZ's on the back).
Times? Don't know, don't care. (Not the point of the data logger).
BTW: I also learn't that I can fit to front tyres nice and cosily in the front seat
The front brakes didn't get too hot today, the heat haze cracking on the disks didn't get any worse (but I was being gentle on the brakes)...I do need to clean the grooves out!

That Porsche driver was proper aggressive. Everytime he flashed past he was mugging a gaggle of cars in front.
The highlight of the day had to be watching him overtake everyone down the start finish straight on sheet ice God knows how he managed it but I just cringed thinking this is going to be one seriously expensive crash.

Not sure God had much to do with it...I think he had some computer assistance!

Bat should be ashamed of themselves and offer a reduction to all who attended off another trackday. Otherwise they will lose bookings in the future no questions.
If no one tells the organiser at the time - he is powerless to fix it.
Of course you did complain to BAT immediately didn't you.
Sorry - not trying to stir it - I can really feel the frustration.
But I feel for the organiser here too.
