Can he do it standing up

My preferred method is starting in 2nd, shutting off the throttle engageing the clutch and grabing a handfull of throttle whilst re engaging the clutch. And up she comes nicely.

Whilst learning to do the above and to guage the correct amount of throttle needed/how far up to bring the bike and generaly get comfortable with being on the back wheel. 1st gear is ideal.
