- FT frequency = FTM / FGA
However, there are severe problems with the equation – in fact so severe that the FT factor should be split into two.
Four Factors, developed by Dean Oliver, is a widespread concept in basketball performance analysis. Yet there is a serious flaw in it: it uses eFG% to measure the efficiency of field goal shooting. This is an invalid procedure, as shown here.
What then would be a valid indicator for the efficiency of field goal shooting within the framework of Four Factors?
