If I were to take another wild stab, it seems they've pegged 50% utilization as the max they want to allow. For example, when I was there, a D3 modem was highly recommended (though not required, at first. Later on all new customers with Turbo were given D3 modems). Single channel is good for about 38mbps theoretically. 15 is less than 50%, so standard is fine on a D2 modem. But turbo is 20, which is over 50% of 38. Same thing with higher tiers. In "MAXX" areas, turbo is 100, which is the maximum they'll allow on a 8 channel SB6141. The next step is 200, which is again, more than 50% of that theoretical 350mbps max.
Same thing again with the 6141, the max they allow it's use for is the 50mbps. They don't allow it for use with the 100mbps service- again more than 50%.
I can't confirm this, but I am taking a guess that 50% or less of maximum theoretical capacity is what they are aiming for.
