@MarcusBrown why are you hatin' on Greg. Not saying he doesn't need lasik, or that he doesn't deserve it, and I suspect it's all in good fun. Somewhat. But, well, just but.
IMO, entry gates are overrated. However, I suppose if they're there, and the rules say we have to go through them, then I guess we should. But it's not a super big advantage to go early at the shorter line lengths. Just my opinion.
The missed call can go the other direction too. At 2008 w. regionals here in the NW my main ski buddy of 35+ years ened up second due to missed gate, and a missed call to the guy who ended up first. I think the gentleman lurks around the forum here a bit. Anyway, he didn't totally give up skiing because of it. It happens.
