Does anyone else ever have the perception that each pool has one direction that is "faster" than the other? I swear that this is true, but can't really imagine the physics of why it would be so. In particular, it seems to me that going from the deep end to the shallow end almost always seems "faster" than going from the shallow end into the deep end. I speak specifically of 25 yard pools with one end about 12 feet deep and the other end about 3-4 feet deep since I have little experience with anything else. In all cases, the water jets are symmetrical in placement and seem to be pushing out the same amount of water (roughly). These are also indoor pools, so there are no wind effects and we aren't talking about when the water buffalo...err... water aerobics people are creating tsunami in the shallow end.
Or am I crazy? (No cheap shots on that one.)

I have to agree with this. Maybe it is the perception of speed, like the way flying in a plane at altitude feels slower than when you are just above the runway.
I would figure it would be slower going from deep to shallow, rather than the other way around. I am thinking about the ocean moving towards a beach, and you start getting waves breaking, and currents as you get shallower.
