In the good old days when WES and a couple of us other ancients were in charge (maybe even HOWARD and definitely COACH) there was an initial 'round' called the 'relaxed round' and each competitor had to stand facing front fully relaxed .... and this round did not continue until each competitor was completely relaxed.
And this relaxed round would continue after the head judge said "Turn to your left", Turn left", "Turn left" .... and finally face front.
On each turn each competitor had to be relaxed or he wound be corrected.
By the time each competitor had completed the relaxed round ... each judge would have each competitor ranked from first to last as so noted on each individual judge's unofficial worksheet.
The second round would consist of the mandatories while in a lineup .... and during this round the judges would 'improve' and make changes to his decision during the relaxed round.
Yada, yada, yada .....
And then the interesting tabulation process comes into play ...;. but it hurts my brain too damn much to go into too much detail after too many Tequila shots in celebration of St. Patrick's day ..... so I'll turn this over to Howard who knows this shit pretty damn good ,,, but probably not as much as I think I do.
