It is the perfect way to find out what PB is worth with no other degrees of freedom in the experiment. Different programs would break the experiment as you start off with two variables, (a) program characteristics and (b) PB on/off. using two programs is an ok idea, but this approach does highlight the difference between PBon and PBoff pretty clearly.
