It is always good to be realistic. The Madrone’s FBI (Family Brass Indicator)
helps in this regard.
First determine numbers: Only include those relatives who would take one on the jaw for you.
For each qualified relative figure
How strong are they –
How many pounds of lasagna each can eat at one sitting?
How fast are they?
Assuming no traffic, how many exits of the LIE or some equivalent expressway can they cover in twenty minutes?
IF there is traffic, how willing are they to drive on the shoulder and cut in when it runs out?
How mentally tough are they?
When they curl their nose, how far do people back off?
How fiercely will they fight?
Like Al Pacino in Scarface?
Like Ray Liotta in Wiseguys?
Like Robert DeNiro in Meet the Parents?
This will give you some idea of how much back up you can count on.
