>Flipped WRT what? They've run the experiment at differing times of the day when the experiment is effectively flipped WRT the helios. It's "flipped" only with respect to the center of the earth. Since this isn't a point of measurement(the satellites are the ones effectively holding the stopwatch), it's not really worth taking into account. If the neutrino stream was going west->east(i.e. with the satellites) rather than east->west, the receiving station would appear to be moving away from the starting point of the neutrino stream. That would effectively decrease the speed of neutrinos.
