I have seen people stringing where they weave through 2 holes and then do a tension pull. I feel this is not accurate as the grommets will reduce the actual string tension on the previous string. I string all racquets pulling each string individually. This takes a little more time but I know it is accurate. Still I am able to string a Babolat racquet in about 20-22 minutes. I also straighten out the cross strings too while I am stringing so the stringer can adjust to the extra slack. I am really curious as to how some of these professional stringers can do a racquet in 12 minutes. Are they doing it right or are they cheating by not pulling each string?
