As a rule, competition pilots do not cheat, and do not like cheaters. Some rules maybe difficult to police, but even the existence of them strongly discourages cheating. If we make only rules we can police with 100% certainty all the time, we are left with very little. The wwgc penalty send the exact message IGC discussed in previous plenary, ground controlling is not what we want in this sport. I seriously doubt any team will risk chance of penalty in future competitions.
