I'm thinking it looks "exactly at 2s" simply because your plot only has data points for only 1s, 2s, 3s, etc. A high ADEV bump near tau 2 s suggests a phase modulation around 4 s. If you look closely you can see this in the phase plots; it's somewhere between 4 and 5 seconds. It shows up in the power spectrum near 4.4 s.
