DirecTV has been using the viewership numbers from August. The month with no bull riding, no college football, no Tour de France, no Indycar, and no hockey.
Still, what's an acceptable number to make people pay for? Certainly there are channels that are less popular than Versus that are still getting our collective subscriber fees. Even ESPN doesn't reach 25% -- on October 6th ESPN
hit 21.8 million viewers for Monday Night Football -- the
most viewers in cable history.

So the most ESPN has ever pulled for viewership is 21.8 million people, yet 98 million people are contributing $3.65/mo to have access to the channel. By my math that's 76.2 million people paying $3.65/mo for a channel they don't watch!
Versus isn't doing nearly that volume, but they hit
3.45 million viewers during their broadcast of the Stanley Cup playoffs. The channel is (was) available to about 75 million people, so that means that 71.55 million people are paying less than $0.30/mo for a channel they don't watch.
Out of a channel package of 200-250 channels, people generally only watch a handful of channels. The argument that always gets made here is: ala carte! People couldn't afford ESPN if only those who watched the channel wanted to subscribe to it; they'd need the same supporting revenue they're getting from 98 million people to maintain the quality of the broadcasts and they'd have to get that from 20-25 million folks. Networks like Lifetime would fold without enough viewership to support the channel.
The system isn't perfect by any means, but I don't think there are any obvious ways out from it.
