This actually sounds pretty reasonable.

Now I'm wondering if they'll continue being reasonable with a clear commitment to a specific speed, or - at the very least - a decent and reliable average.

If so, they'll be in a position to run marketing campaigns where they start assaulting those godawful "up to" claims by demonstrating what their competitors actually average.

Alternately, this really is about offering less for more. I suspect we'll know one way or the other within six months.
