Oh Lawdy. Did a little more perusing and came across this thread in shotgunworld forum from about 10 years ago talking about square loads. Lots of good debate and them boys played rough with one another.
Again nothing definitive but I did like the discussion about how well 16 ga and 28 ga perform at 1 oz and respective 3/4 oz loads as these two gauges seem pattern well and have less shot string. Anyway. Sounds like it is a healthy debate and you can read their discussion if so inclined. I swear if some of those guys would have been in same room it would have come to fisticuffs if they talked that way in person.
