Vaibhav5viv: The lower level ATV goes 50-77-93
50-77-93-98-115. Looks pretty tight to me. 60W punch between the 53 and 77; 56W punch between the 77 and 93; pw punch between the 93 and 115. Doubt you'll get much tighter than that.
In your case, because you already have the top CGs, you cover 52,60,68,80,84,100,115. How are you getting tighter coverage than that.? Certainly not by moving away from the 3 degrees in this discussion.
