So for 3.5+ and 7.5+ when would you call a foot fault if you are singles and doubles? How do you do it nicely? Now I am the guy that will let you replay if you found my serve out if you failed to call... one or two times, then it is your fault. So i try to be accommodating. At the same time I do not bunt my second. I hit a Flat, Kick, or Slice, from a pinpoint stance so its clearly in or out. The other guy/gal has one decent serve then a bunt that he/she foot faults on.
