I'm responding here even though it's Thursday because I don't see a condo yet ;-)
I don't think we need to set a specific number at this time. We play it by ear since you've been here a bit. So, when you get a number lower than what you've shot before, just post and ask for help. Be sure you make it clear in the subject line that you need help by adding something like "Stalling Need Help!" to get attention and don't be shy about bumping up your condo if you need to (just open it, click on "post reply" and then type "bump" in the text box and hit "submit"). At that time, we can discuss what you have going on, if you will be there, etc. so we can tailor what you shoot to the situation.
If no one responds, which is unlikely but can happen, then read over the "Dealing with Low Preshots" sticky that is linked in my signature block. I think it's a great idea for you to print that one and the other one on "Handling Low Numbers" and have them in a notebook for quick access if you need them.
