It's actualy quite rare for this hull form in out and out racing.
The term 'Deadrise' when used as a generalisation, is refering to the depth of the 'V', usualy quoted 'at the transom'.
'Constant deadrise' refers to a hull with a deadrise that is substantialy the same at the transom as it is in the forward section. (by far the most common form for all out racing)
A 'Warped Deadrise' refers to form you described with a deeper 'V' in the forward sections, than at the transom. This form gives a very soft and 'pitch stable' ride.
