Current rule reads:

A formal challenge has priority over all other challenges.

Exception: Top Ten challenges have priority over a formal if the top ten challenger is higher rank.

You are allowed to use the formal challenge only once every three days. Formal challenges are there to help you ONLY if you are unable to set up a game or you are on at different times and need to set one up. It is not to be used as a way to consistently get up games. You should try to get a game first via all other methods (challenge in lobby or friendly e-mail request if in top 10) before you issue the formal challenge.
