I habitually ( ) do a 'partial overlap' where towards the end of the braking phase, I dip the clutch, change gear and then before I lift the clutch, I am off the brake and my right foot is available for rev-matching if required. Personally I find this make for a smoother, more flowing drive as I don't have to lose all my speed before changing gear. I used this on my IAM Masters test and the examiner didn't comment on it at all.

I think this is the issue. I've been told you must SEPARATE. Speed then gear.
I think you're entirely right in what you're doing, thats how I do it. The system I've been taught feels unsafe to say the least.
Rick101 wrote:Yes, sorry it's separation that is the issue.
I have been told no overlap is allowed whatsoever.
1 Brake for corner.
2 Come off brakes.
3 Right foot over gas (car usually near stall by this point)
4 Disengage clutch
5 Change gear (usually 3/4 to 2nd)
6 Engage clutch
7 Then begin turn
Nobody from IAM has mentioned rev match, The only time I've heard that is from people on here
I understand why you wouldn't usually trail brake into a corner but I don't see why you can't prepare your gear change, i.e 4 & 5 whilst under braking. As long as the clutch is disengaged and you remain in control of the car (braking not coasting) it doesn't really matter what you do with the gearbox surely.

Ahh John have you not heard of it? It's a racing technique used by Lewis Hamilton sometimes when he's out qualified by his upstart team mate.
(oooo controversial!)

Be my pleasure John!
PS. 'Head and Toe' is a close derivative of another VERY advanced technique of...

Personally I'm not in favour of the use of overlap (with partial separation or heel and toe) if it is used to get round slowing enough and early enough for a bend.
