Flat Patterned Helix Challenge - unsolved so far......

Hi there,  I am wanting to create the flat pattern, laser cut part of the attached variable gradient helix.  It is basically 200x5 flat coming into a helix at 25.5° and exiting at 19°.  The main bit I am after is the hellical part and its true flatterned shape.  I can do it for constant gradient throughout the helix i.e. same gradient going in as coming out but seem to be stumped with this one.  Any ideas?
