there is no normal for an individual table as they change based on many factors in its environment. but you can figure out those quickly with a couple shots.
but there is a normal with all tables and that normal is for the table to roll properly according to its diamond system. that is why there has been a standard to tables to play with the diamond system.
if you just got one practice shot before you play, make it a cross rail bank two diamonds to one at medium speed. that will tell you most of what you are facing that day and table.
