How to set the calibre 3220?

I am reading the directions for the calibre 3220, but I do not completely understand them.
Can anyone explain this detail:
"For the minute and small second hand to synchronize perfectly, the minute hand must be 30 to 40 seconds ahead on the desired index"
Say I am trying to set the watch to 1hr 23min 00 seconds: Does this mean that if the second hand is on 0 seconds, the minute hand should be set just past halfway between the 23rd and 24th minute? Or does this mean something else?

Thank you!
