Agreed. Their actual vs predicted values are available on their site going back for several years.Touring plans does their own 'self-critique' on a daily basis. They will list what their predictions were and what the actual crowd / wait time was for that day.
I'm here now during Easter.The crowds are pretty sensible (6-7) and they were the only site calling for sensible crowds. We were so surprised at MK - followed the plan verbatim and pretty much walked straight on every ride. We still booked FP+ and did use them but didn't really need to.Touring plans does their own 'self-critique' on a daily basis.

I checked the historical data for the week I was there last year and it seemed like they were pretty close. We have personalized plans built for all 6 park days in a few weeks through their site, looking forward to seeing how well they work.
Even on low crowd days, the most popular rides (SDMT, RnRC, TSMM, etc.) all have long waits (i.e. 45-75 minutes) after 11am. Why wouldn't you use fastpass?
