I have seen people holding the lever up (giving an extra inch or so of travel above the last 'notch') and claiming it makes all the difference.
Hardly 'Drivel'. I'm sure it makes some difference, but if you feel you need to do this to get into a strip, maybe you shouldn't really be going there at all.
In that situation I think your hand would be better on the throttle ready to go around.
