The first flight in the video of Bill Werwage flying Juno appeared to me to be pretty small diameter turns in the squares (I can't even complete the Beginner pattern yet). I wonder how they compare to today's turn diameter. Maybe one of the expert flyers could comment on the turn diameters.
It was fascinating to watch the maneuvers. Brought back a lot of memories. As to your question, here is my take. There were two camps back then and both seemed to score equally well.

One camp was very corner and elevation conscious, shapes suffered. Corners were tighter (around 10-12') and maneuvers at 45. Another camp was very shape conscious and flew beautiful maneuvers around 50-60 degrees with corners closer to 15'. Some, like Werwedge combined large with tight corners which made for some remarkable square maneuvers.

Dallas was a battle ground for both styles. You had Gieseke and Rabe giving us the best of both styles. It was a fun time, probably our Golden Era.
Today's patterns are much closer to the rule book and IMHO about 25-50 points better at all levels, mostly due to the equipment.

Others will probably disagree but we all tend to see things different even when we are looking at the same thing!
