Tons of time to be saved but first try at doing all of the endings back to back in one go. Time stamps for start/end of runs as well as the total playtime for each run is in the description of the YouTube video.

I really don't like doing the picnic run lol

I also didn't add in the ms, if we want to add ms to these long runs, I can recalculate for that. Right now it's just the minutes and seconds added together for each ending.
