36 through 48 = 80MHz in UNII-1
52 through 64 = 80MHz in UNII-2
100 through 112 = 80MHz in UNII-2-Extended
116 through 128 = 80MHz in UNII-2-Extended (If usable because of no Terminal Doppler Weather Radar in the area)
132 through 144 = 80MHz in UNII-2-Extended (I understand that 144 has some clients that don't support it)
149 through 161 = 80MHz in UNII-3
If you map the DFS channel numbers you provided to the 80 MHz mappings, it looks like you would likely have a 6 channel plan. Keep this in mind, the wider the channel: 1) the higher your noise floor and 2) the more likely another AP / client in your system or another wireless system overlapping your channels that could cause contention and a back-off.
If you're concerned about the design, I would recommend contacting the ACE Engineer you worked with. I believe they would likely be happy to explain the reasoning behind the 80 MHz width selection.
