same start, same finish in that corridor could be completely different within a 10 minute period.
Remember currents and tide predictions are only that... predictions. It is not an absolute science as there are too many variables.
But you reduce the variability by only comparing swims that start and end at the same place. You're coming from a different direction if you come from the GG bridge rather than Alcatraz. But I'm done with this back and forth, so keep insisting on comparing apples to oranges if you want.
