'Primary projection' means distance beyond the tertials - correct
But the distance beyond tail is the 'wing projection' (given the wing is longer 
than the tail)
If the tail is longer than the wing there is a 'tail projection'

'Primary projection' particularly usually means distance beyond the tertials 
but may also refer to distance beyond tail.
