Two points:

Elmira flying is very different than the flying in Utah, or in the west in general. Thus the results of Elmira are not valid universally applied.

Hasn't the ICG already concluded that the current stealth mode does not provide enough situational awareness, and is not acceptable for mandated use due to safety, coupled with the fact that the company that developed and makes Flarm recommends against the use of stealth? This is why the IGC is working with Flarm to develop a modified stealth mode that provides more situational awareness while removing tactical information?
