No known cap, and even if cors are there or not regularly, i took a quite realistic example to show that if the cap were 50% it would be quite reachable, Even without a warrior, 50% double attack is still reachable. I took the model is was presented (Cor + RDM + # of DDs, not to mention WARs are out in force as of late last i checked...) Not to mention in VW that party isnt that unrealistic either, though would be a bit silly in my opinion for the layout of one of your 3 parties.
