I think many of the problems with zero beating can be explained by packet/internet spots.

If you're on 7030.5 and someone spots you on 7030 or 7031, then 7030 or 7031 is where a lot of people will start looking for you.  If they use their RIT to find you (up/down 500 hz), their transmit frequency will be way off.   

Pretty sure that most contest software allows for spots to include at least one decimal position, but inexperienced users may not realize it.
