Dude, I do what you do on my ZDZ80. I keep going back and fourth. First the center nut then the bolt circle. Just snug them up good. There will be a point where they are all snug. Stop at that point. This may take about 6 times for the nut and 6 times for the bolts. It is a good idea to recheck them periodically. In fact that is what I'm going to do now since I'm going to a flyin tomorrow.
