Maybe also mention that on most low tail aircraft, there will be downwash from the wing
hitting the stabilizer creating a downforce. The higher airspeed, the stronger the downwash
and more downforce.
Not exactly true - the higher the airspeed the lower the wing AoA and the lower the downwash angle at the tail (which is usually about 40% of the wing AoA)
Plus of course the fact that downwash doesn't change the force on the tail needed to balance the airplane - it just changes the tail/body setting necessary to generate that force.
