Not familiar with FAA techniques but if you don't pull all the available Tq then how can you call it a 'Maximum Performance Take Off'?
Normally a MPTO would be required when power available was marginal so using all you had available would be the natural way out. IMO if you are in a confined area you use a vertical if conditions permit but when push comes to shove and space permits you try your best to get translational lift (15kts) then haul the nose back to hold about 35 kts which will approximate the Best Angle of Climb speed. I used to teach confined areas in Sea Kings and I wouldn't necessarily say that such manoeuvres were using the bottom half of the 'skill meter' but with practice you can get that technique weighed-off and make it very effective.
