I looked at Benny's video several times, it's still very clear his head comes out before he touches the wall. I even tested under different scenarios, including looking at it from 20 cm away, standing 5 metres away from the screen, squinting, standing on my head, after drinking a few good Aussie beers

and then all of the above....
in each case it's still a white card but hey that's just me
Nice dynamic technique Benny !
Cheers,
Wal
