I am not in a good way for analysis (given the fatigue brought on by the day). This week was better than last (only recently were things becoming quite clean again). So, as it stands, I think it is just an outlier in the data, as it were.
The workout situation is not well researched, but there is enough out there (besides my own experience) to discredit being previously aroused. It seems to do mainly with core muscle exercises. Little is known, but in short, the muscles just react violently enough to cause stimulus. When this first happened to me, there was no PMO on the mind.
