Just passing along my experience today (Saturday) at Epcot:
Test Track: got in line with two people in front of me at FP+ checkpoint one so no line outside at all. Walked straight through to FP+ checkpoint two where there were 6 people in front of me. Total wait time from first getting in line until scanning band at checkpoint two - under two minutes. Stand by wait time was 50 minutes.
Soarin': got in line with no one in front of me at checkpoint one. Line stopped with about 20 people or so in front of me. Waited a few minutes to scan band at checkpoint two. Total wait time from getting in line until scanning band at checkpoint two - 5 minutes. Stand by wait time was 70 minutes.
Mission Space: no one scanning in front of me at either checkpoint so total wait time was under a minute. Posted wait time was 20 minutes but this was probably inflated as line seemed closer to about 10 minutes.
In total walked in to Epcot at 1:30, had lunch at Boulangerie, rode three rides, bought Mickey ears, and walked out by 4:35 to head back to Resort.
