One small comment. In pattern it takes a 15 degree deviation to earn a 1 point deduction. In IMAC you get a 1 point deduction for a 10 degree deviation. So, in that sense, IMAC uses a more stringent standard for awarding deductions.
Pattern and IMAC both judge track and not heading, so I'm not sure what you meant by the heading reference. Same goes for wind correction. And again, for all of these things IMAC uses a 1 point per 10 degrees versus 1 point for 15 degrees.
Pattern does use a box and since IMAC does not, the pattern scoring is certainly more stringent in that regard.
