Many leagues enter a starting handicap in event #1, which
automatically carries forward from event to event until a "calculated"
handicap is established.
This is by design...LM does this to save time for most leagues.
Note: If you have instructed LM to NOT calculate a handicap until a
golfer has at least 3 scores...there is really no need to "lock" the
handicap. LM simple uses whatever handicap you type in.
You only need to lock a handicap if you need to "override" what LM is calculating as the golfer's handicap for the particular event.
