the tried and tested method that has been used ever since musical annotation was first put in the printed form I take it that measn putting the chird above the appropriate place in the text.

In which case you cannot go wrong just doesn't apply, when you are doing it via a computer which adjust the exact place it puts the chords. Though if you listen to what you are playing, and are ready to adjust what you are seing to make it sound right, it's easy enough to sort out that kind of thing.
