[See corrections in replies; “think for five minutes” was in EY posts as far back as 2007, the HPMOR chapter was in 2010, and the first CFAR retreat (though not under that name) was 2011 IIRC. Still curious to know where he got it from.]
Before HPMOR, “think for five minutes by the clock” was a CFAR exercise; I don’t recall where they picked it up from.

Before HPMOR, “think for five minutes by the clock” was a CFAR exercise; I don’t recall where they picked it up from.It came up in the sequences, e.g. here, here, and here.
Also, chp 25 of HPMOR is from 2010 which is before CFAR.
I think this part of HPMOR predates CFAR?
