said by telcodad: but in my area, Comcast's current, regular charges for the Extreme 50 and Extreme 105 tiers are $99.95/mo and $199.95/mo, respectively, so I can't see why it wouldn't be "economically viable" to allow those few customers to use 1 or 2 TBs in a month.
Because that assume no little cost for the high speed tier itself, i.e. if all the excess is due to data cost, shouldn't we all have 105 and the tiers represent allowed volume?
but because of the way tier system was designed and until now marketed, I think the current prices represent the really price of that speed with ONLY 250-300GB included, now the choices are to decide where the baseline is and exactly how to price the overage.
Remember tolls serve 2 purposes, the first is to repay over time the true cost of the improvement they pay for (plus profit/interest for the bond holders) but the pricing also limits the useage to fit the existing/expanded infrastucture.
so you look for 2 points in the potential pricing range, A}which is maximum return on investment and B} most efficient uses of the infrastucture i.e. moves the most traffic at a high but not always fastest speed.
Somewhere between those prices is usually the best pricing choice for everyone.
