Earth, I'm inclined to agree with you as I've been busting my ass trying to better my GTR time on free run and only last night managed a time about 0.04 from your own with a sixaxis. I have to admit the challenge and motivation to post the fastest time is making me dedicate a lot of time to this, so I would love to find a reason why the others can pull out about half a second on my time...but I'm reluctant to blame it on this. I just find that the more I practise, the more time falls off. If you had asked me 3 days ago there was NO way I could see me shaving 0.4 off my earlier GTR time...and yet there it went.
Now I could be dead wrong, and I could purchase a G25, change the brake balance and torque distribution, and slap in a 2:09 or 2:08...and yet I know with the lap that I did, I messed up 130R so if I chain together all the best sectors I have done so far, it would be a 2:09 anyway, with a sixaxis.
I'm just a little reluctant to latch on to something like this and blame it for the current few tenths I'm missing. I may just have to give credit to people like Timo and Chronos who could string together 3 perfect sectors regularly.
Really??? Ok now I'm really annoyed I am going to be away from my PS3 for 4 weeks because I may never get a chance to test this out and see if it improves my time

Maybe Earth can experiment and see what happens? I'm assuming he is on Sixaxis also..
All the best
