A bit of a rough start crazybadger but, it could have been much worse if Rasaman had been a selection. I hope you don't mind me throwing my 2 cents into the mix as I know it's only fun but, your staking is already far to high for the average prices of your selections without adding an additional half point. Also, even if the staking was where it should be it is probably a bad idea to vary your staking depending on what the previous selection did.
You probably need to clarify what you're are going to do incase of non-runners as when you start betting proper your bet will already have been matched unless you're going to use Betfair SP and even then unless you're at your computer during the day you won't be able to cancel the selection if non-runners bring the total selections to under nine.
I'm only saying this as from reading your first post it sounds like you're maybe intending to bet these for real in the future, which may mean the results your're getting in this thread may differ to what you'll get when you start using real money. Rasaman being a prime example.
Best of luck.
