2 Trip Aliens Notes

(timings are for when the milk road boulder is NOT there)

soar to milk road owl for the first time at 3:25 to shoot aliens before 3:49 (takes ~24m igt from owl > shoot wave of aliens)
can soar away from aliens at 3:49/3:50
2nd wave of aliens hit barn at 5:10/5:11
have to be at milk road owl for the second time at 4:46

you have about 56m igt to soar away and do stuff
gossip timestop could give some extra igt to do something if necessary

56m igt is about 42s real time
(if you're going to invert time after aliens anyway, then could just invert earlier and have 56*3 = 2h48m "uninverted" igt)

if the thing you soar away to do is NOT an extra soar, then 2 trip aliens has the potion to save ~20 (assuming song of soaring is ~22s) over just standing there doing nothing. Keep in mind that the some runs, like 100%, don't just stand there and do nothing, instead they store SoDT and park epona, which would make 2 Trip Aliens much less worth it. If the thing you're soaring away for is an extra soar, then it's slower to do this.
