If the time slices are 1-2 and 2-3 (or 3-2), will the timing of event 2 introduce a bias? Currently its: 1-2 vs 3-4 7-8 vs 5-6 ... If event 2 is being used as common, would it then be: 1-2 vs 2-3 4-5 vs 3-4 ... And so with this second set, you can see that 2 is common to both times of the first bit and 3 is common to the first and second bit (and 4 is common to both times of the second bit). If there is a systemic error in the system, having those be common timing events might make it worse? And I'm guessing there.
