Well, that is what was posted.
On Friday 4/30, Hagrids line said 75min, and was straight up walking to Hagrids hut with none of the switchbacks in use - I walked off the ride at 30min.
On Mon 6/2 afternoon I walked past Hagrids while they were posting 120min wait. There was absolutely no line before the lockers (past that, you can't see). That makes it a 40 min wait tops, assuming no breakdowns. I went on FJ with a posted 50 min wait and was walking off at 20-25min. Hagrids is the easiest to tell before you get in line, so you can make educated decisions.
Why they continue to post such inaccurate times mid-day boggles my mind.
