I think that part of the problem with television, is that far fewer camera crews are being pemitted in each arena than usual. So BBC just has two sports on at the time.
Suppose I am feeling fortunate, as the two sports I have most interest in are Artistic Gymnastics (Men and Women) and Diving, both of which are getting excellent coverage.
Feeling slightly nostalgic today as I watch the Mens Team Finals as I rememebr this day in 2012 when I was fortunate enough to be able to be in the Arena when the GB boys took their historic Bronze Medal (first gymnastic medal for GB since the 1920's, and also the first medal for Team GB of those wonderful Games.
