Hi Craig,
I have been involved in the Winter competition, and posted mostly on a Wednesday or Thursday and ended up with results that I was happy with, whether the team was is another story. Something that I would suggest to you is, add two scratching alternatives with your selections. If you only put one substitute in with your selections, and have two scratched out of your three selections, as happened to me a couple of weeks ago, there is only one horse running for you in the race.
Good luck.
Robert
