Race pattern.

if you do it, get on the bike, and sdtart riding, think about each gear change for a while, don't try to press on, but use a bit of anticpation of what yoyur next gear change will be - usually you can on the track...and put your foot in theright place for it.

I found I got better gear changes on the exit of RIGHT HANDERS with a race pattern as I was hanging off and had a problem getting foot under lever.

Works a treat now - wouldn't go back.
