I really need to Second this post.
To be clear Fastpass and standby go to either dock at Pirates of the Caribbean.
None of the three theaters at Soarin are dedicated to Fastpass. All three take passengers from both lines.
Space Mountain will send standby passengers and Fastpass passengers both sides.
Big Thunders merge point is actually prior to the point that the line is split for the two load stations. Meaning once the Fastpass guest or the standby guest is past the merge point, they choose which of the two lines to get into.
Operations is a no way sending empty vehicles on the Fastpass side while the standby side is backing up. This just is not an accurate accessment of fast pass.
I agree for the most part although I have seen at Pirates FP sent around to a loading station that loads from the right while standby is sent to another loading station that loads from the left.
