Hi Daniel,
thank you for the explanation about different bases. These are 15-minute runs in a monkey, so I think that making an assumption of negligible movement between epi[0] and min_outlier, which may be anything from epi[2] to epi[409], may be too risky. I will probably revert to epi[0] for both.
I had thought that maybe something is going on with the file system, and I did try inserting a sleep, and it was sleep 10. Same result...
