People seem to get particularly upset about ratios in SFI requirements. The argument almost always degenerates into bit/miles and “we’ll meet you at your specified points and we’ll cold-potato.” All these miss the salient point: the SF part of SFI is not based on bit/miles and meeting points. People always argue based on cost, when it is really based on value. Ratios in the end are just one data point in the equation.
