Start at the middle two bolts and slowly work your way back and forth to the outer bolts/nuts. Do them at 15lb/ft, then 30lb/ft, then final 45lb/ft. after it has been fully warmed to operating temp and has been driven, recheck them at 45lb/ft. 
There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Another quality post.
