Ties and such

Hi: My first handicap event scored with few problems. It did take some
thought to work out how to set the start times for each Fleet and it
certainly wasn't initially obvious how to set up Start 1, 2, 3 for
each Fleet for each race.
A second (non)-problem showed up. By the end of the regatta we had a
number of tied scores. Sailwave dealt with them correctly but I
couldn't find anywhere to alter the tie breaking if one wanted to. Can
one alter the tie break method?
And finally a dumb one. I miss estimated the number of competitors
when setting the regatta up. Normally I don't enter a number
beforehand and just add competitors. This time I was left with four
"non" competitors but couldn't find a way to remove them. Trying to
delete them on a boat moving vertically 6 feet up and down was not the
place to try! It was just a nuisance on screen.
Thanks, Donald
