The "posted wait time" system is based on guests going through the line while wearing red card lanyards. The information gathered from that system then gets translated into observational estimates. ("When the line backs up to this garbage can, it is usually in the XXX minute range.") Inasmuch as the Pandora rides are fairly new, the CMs are just now getting a handle on what the external markers mean in terms of translating to time. But all in all, the red card system yields accurate results and Disney has no real reason to fudge the results. There is nothing to be gained by reporting 190 minutes if the wait is really 60. All that does is discourage people from joining the line which in turn sends them home without riding the ride which in turn causes them to have a negative reaction to their trip. Conversely, posting a 60 minute wait when the actual wait time is 190 minutes does the opposite. It encourages people to get in the line which in turn causes them to kill over three hours in line which in turn causes them to ruin their entire schedule for the day which in turn causes them to leave with a negative reaction to their trip. Bottom line...conspiracy theories about "cooked" wait times always exist, but there is no basis for them. Disney tries to be as accurate as it can be and has no incentive to lie. (With the possible exception of the very end of the day where they might very well want to discourage people from jumping in line 30 minutes before the park's stated closing time and therefore might exaggerate the wait times as being longer than they actually are hoping that guests won't shoot for that "one last ride" and will go home instead.)
