well, all day
I am watching it bit less in the morning (croatian time: +6 to +8 hours in relation to USA), mostly just switching channels to see if there's anything interesting, and then watching bits of qualifications and stuff...
In the afternoon and evening - all time
I watched all swimming, now all track & field, lots of team handball and basketball, and of other sports - what pops up
Yesterday I caught extra time of USA-Germany women soccer, and also gymnastics just in time to see how Alexei Nemov was robbed.
