Calculating web app downtime on a per-user basis?

My employer is looking for a more accurate way to calculate downtime in web applications. Right now, we calculate in minutes of overall downtime, but I feel it would be more accurate to count "user minutes" that are lost - 20 mins of downtime when there were 10 users on the system is far less important than 20 mins of downtime with 500 users online. Is there a standard out there for doing this?
We have about a dozen applications, all of which have different total numbers of users, with different usage patterns. Has anybody done something like this, and can recommend how we can get more useful metrics?
