Originally, the FactorSpace.Size function only returned the total amount of trials within a list without taking into consideration the assigned Weight of the trial(s). The FactorSpace.SizeWithWeight function returns the total amount of trials within a list as well as includes information about the Weight of the trial(s).
The value of Weight for each level is considered. For example, the SizeWithWeight value of the following FactorSpace representation would be 6 because the Weight value of FactorLevel 4 is 2. The Size value would be 5.
As the trials are run, the SizeWithWeight value decreases.
