You know, after reading all these suggestions for sensors, and turnstiles, and counting cards, and how to compensate for wheelchairs and people who drop out of line ---
I think the current system of using the card and applying averages is quite sufficient. I mean, I KNOW I'm going to stand in line, and if the wait says 45 minutes, and it turns out to be 50 minutes - big deal! Wait time is not critical to my day, and if a wait is LONG, i'll skip it. I'm not going to schedule my day to the minute around wait times.
I think it's nice enough that they go to the effort to tell us approximately how long a line currently is. The last thing I want them to do is pay for expensive systems, then up my ticket price, just so that I know to the nearest second, how long I'll be in line
