I think that rather than have a set rhythm of when you do and don't TIE, you should look at your schedule and competition and make a list of games that A) you cannot win

you have a chance and C) will win for sure. Then TIE all of games in the A column and the less important games in the B column (games against eh other conference, for example). Normal the games in the C column unless you are good enough to beat them using TIE. Save your CT for TV games, rival games, and other important winnable games.
Once I scored a basket that still makes me laugh.
