I am fairly certain that rules do not prohibit straight-line controls, while precedent and best practice DO’s and DONT’s for course planners certainly suggests to avoid such set-up. It is one thing to fall for course planner’s traps where route choice is important. It is different if course setter’s intentional or may be even unintentional “trap” is a mere instance of eyesight in an area with dense detail and map-flip for that matter. I would even understand if straight-line instance was in the middle of a section… but right after the map flip… not good. And precedent in high level IOF races suggests that Inspector should have picked this up.

I remember how inspectors (almost entirely Swiss by the way) during 2018 World Championships in Riga went out of their skin to not allow straight-line controls during a sprint competition.

What has changed since then?
