On his Twitch page, DerplingDiamond claims a time for EPF HR of 38:52. When I asked him about the run, he said he didn't record it, which is understandable considering it's DS.
Unfortunately Derpling died in June last year (see here) (Edit: Tweet is gone, see here instead)
Due to his runs of All Missions on the Web version of Club Penguin, I find his EPF and EPF HR runs believable (and the fact that I got a 39:08 yesterday). The main point of this post is that the 38:52 is the run I have generally been comparing myself to, and the run I reference in the submission text of my 39:08, rather than the runs currently on the leaderboard
Well, now that Derpling's run has been beaten, I think it's ok to finally time to add his run into the leaderboard.
One problem is I don't know the date, I tried searching archived versions of his Twitch page but there aren't any
