A good improvement would be that invitational bids do not create forcing pass (non forcing bids at the 3 level mostly), but inv+ (cuebids or redoubles) do create forcing pass, unless made by a passed hand because then they are just invitational.
I really feel strongly that a bid which is invit+ with a fit should not establish a force since it may be based on shape, not just high cards. It is not comparable to a bid showing invitational values and no fit.
