In my somewhat limited experience, "t" commitment is usually at least 10% of wire speed. Though if transit is coming off low-cost LAN ports in data center environments, sales folks will probably approve lower commits if pressured. Also, some large ISP's have a policy that you must buy the whole pipe unmetered if your commit is >50% pipe speed. And there are at least 4 ways of computing 95th percentile, though I'm sure there've already been threads on this.
