What I usually do is set the hello time to 1sec, and the max message age time and the forward delay time to 4 sec or so.
If you divide the max message age time by the hello time, you get the maximum number of consecutive STP packets that can be lost before a recalculation. Be sure to adapt this to observed packet loss. Twice the forward delay time is the time it takes between a recalculation and a new stable situation (in case of single host failure). So, max message age time plus twice the forward delay time is the failover time.
