Is this an off-by-one? While I'm not acquainted with perl, https://raw.githubusercontent.com/gentoo-perl/genlop/master/genlop has this: "For a better prediction we only consider the last 10 merges", followed by a max() with the number 9, suggesting zero-based indices that would need to be incremented for the average, but then "$tm_secondi = sum(@merge_times) / $#merge_times;" (That said, I also wonder if the "slicing off" part needs adjustment too, can the (zero-based?) length be greater than 9 after it was shortened to be 9? Or am I misunderstanding the code?) Summing the three merge times and dividing by two I get, if I've not messed up my calculations, 68 minutes and 27 seconds, matching your "Currently merging" output. -- Nuno Silva
