The Soarin' test was a hybrid queue, FP+ with a come-back-later line.
The TSMM test was totally exclusionary with FP+ only.
It does seem to be a natural progression of a "what-if" scenario, and I do hope these tests are for a methodology that will only be applied during busy times.
Considering that a large part of the logic in choosing which attractions to make advanced FP's for is the decision to sacrifice one headliner for another by way of using the standby line, the unanticipated lack of a standby line upon arrival has no positive net value.
And to further my point about how WDW is forcing us all to spend more and more time on just 3 daily choices, here is yet another twist:
A new FP+ glitch?
