The Big Question
For me, this is always one of the most interesting and informative sections of the mag, especially as the 3 systems are presented to the panel blindly. However, I wish that the systems were not always presented in ascending order of expense, because the panel must now know this is usual running order thereby introducing a bias to their responses.
How about randomly assigning the running order so that, say, it is equally likely that the most expensive system intervention is used first, the least expensive second and the remainder third? This could make some results even more interesting!
