@Rudi Riet coaches and "prepared skis" are two things that don't fit together
At least on WC level. We all had plenty of good laugh, when people were "sliding" down grabbing b-net on side of the track or slipping down at speed of light, pretending they were planning to slip down this way, but they wide open eyes and mouth and being scared to death expression on their face, gave them away
I'm not saying anything, as I had plenty of similar situations too, and most of time, it's not too much of fun, especially know if it will go wrong, your friends who saw you, will have plenty of material to joke about for next few years.
@slidingmike sometimes inspections are done slipping down, sometimes they make turn or two, stop, another turn two or tree and stop. And normally there's still some soft snow left on top of ice during inspection. After inspection is over and slippers do their job (sometime between inspection and media and coaches need to be on position time), things get more interesting
