Walked what was close to the 2017 winter fest red course to check the operation of UsynligO. Aobut 25 deg F with a bit of strong wind. The system works but for some of the controls the system did not immediately "punch the control", which left you wondering where you needed to go to have it punch. Having flags is definitely easier. I think UsynligO can work if the controls are not things like "shallow reentrents".
