This is purely anecdotal, but in the past few years we have rarely seen other
DAS users scan into the LL queue. If the information from Len Testa is accurate with ~75-80% of users of the LL being DAS users, then I would suspect purely probabilistically that we would see at least a few each trip, if not more. In the three trips I’ve been on this year alone, the only time I’ve seen other DAS users scan in has been on our most recent trip (very obvious since it turns blue instead of green for the initial scan), and we saw this twice the whole week of using DAS/Genie+. In trips prior to this year I don’t recall ever seeing another DAS user scan in.
While I have a lot of respect for Len Testa and what he’s doing, I clearly have some doubts about his source on the number of G+ users allowed per hour. I suspect it’s more than just 300/hr (which is only 5 people/minute which seems super low).
Not saying DAS isn’t being abused, I’m certain it is. I’m in multiple Facebook groups where people ask/provide information on how to get it without actually needing it. Fortunately the groups I’m in delete those pretty quickly, but it’s clearly something that some people are doing.
No idea on a good solution, we use it, however sparingly, usually on top of G+ and it definitely is helpful and allows us to do more than we had in the past, but we’d be fine if they would move to a doctors note or something along those lines were required.
