1. FF is on other side of the court. Line calls you are making on your side of the court.
2. Judging FF requires depth perception along far baseline, which is hard.
3. When your team is getting ready to receive, even if you are the net man, you are (or rather should be) watching the toss to gauge the serve, and watching the opposing net person to see what he is doing... not looking at the server's feet.
4. Um, and how about singles?
5. Can you really tell from across the net whether the server is getting any airtime or not, and judge whether the feet are actually on the ground at the moment of impact? If the feet are even half an inch in the air after crossing the baseline up to the point of contact, that's a legal serve.
I agree that a flagrant
FF can be seen from across the court. Unfortunately there is no clear definition of what constitutes a flagrant FF. That's what makes the whole thing a source of gamesmanship.
