I'm no expert, buy there also seems to be loads more stuff lying on the bottom of the shallow floor than I remember from previous Olympics. Not even sure exactly what it is - large white panels and other equipment that the swimmers don't look that far off touching when underwater (not the robot cameras which are relatively unobtrusive).

digital lap counters to help the swimmers keep track

Thats pretty nice, when I swam the 500 I would have to lift my head to see the lap counter dropping the sign in the pool which messes with your head position

Wouldn’t the underwater camera on a track cause currents?

I could be fully enclosed for the full length and just have a glass top
