There are many ways to measure the volume (Cubic Feet per Minute CFM) of
the air.
CFM = Duct or grille/diffuser (free-area in square feet) X's Velocity.

Wait, also My bedroom is one of the first 2 places the air goes, so it
should be cooler than rooms farther from the unit, correct?

Not necessarily. The ducts begin at the plenum of the air handler
and different ducts will actually have 'higher pressure' or more
potential air flow. the ducts typically have dampers installed
which will let you 'tune' the air flow. you might restrict the flow
abit to colder rooms to permit more air flow to your warmer
room. These dampers are not to be confused withe the flow
adjustment at the registers which blow into the rooms.

Regardless, you could close some of the dampers to other rooms a
little bit, and that will put more cold air in that room.

In the long run, I also don't think it would matter if there were
rooms before your room. It's about balancing the dampers to get what
you want, within the limits that others here might put on things.

There's only one run from the AC? What about rooms on the other side
of the house?

Not the temperature of the air the volume of air.
