Man I hate WISPs that listen to the recommended Ubiquiti fixed-time frame duration recommended settings. It makes for super high latency for customers that drives down browsing experience substantially. The variable-width framing (on sectors that aren't overloaded) is orders of magnitude better in terms of how fast pages load, and is well worth the tradeoff of slightly reduced total throughput.

Also the stupid fixed framing creates a comical smokeping pattern - fixed jumps of (in this case 8ms) the frame duration.
