Mean run time post-sakau II

An earlier anecdotal study looked post-sakau (Piper methysticum, Pacific island kava) exercise recovery. At that time the data set encompassed 217 days. With a larger set of 466 days of data, the seven day recovery time to run duration returning to near the long term average still appears to be essentially the case. There remains, however, some indication that my mean run duration does bounce back by the fourth day, as I had previously believed. The cumulative average, however, does not show a full recovery to the longer term mean for 14 days. There is a drop in the mean run times on the tenth and eleventh days. The underlying sample size is 19 instances of ten days post-sakau and 19 instances of being eleven days post-sakau.

That sample size suggests the drop in the average is real and not a statistical fluke. By the 24th day, however, the underlying sample size is five instances of being 25 days post-sakau. The difficulty with attaining data out in this tail is that I have to forgo sakau for long stretches. That I have done so five times is in itself worthy of note.

Based on my own self-perception, I usually avoid sakau in the seven days prior to a five kilometer run and fourteen days prior to a ten kilometer run.
