I worked it out and it comes to about 1 degree of extra lean in typical cases (using my Quickbeam as "typical"). If you want to play around with the numbers, I wrote a little "bike lean calculator" and put it up here: http://users.csc.calpoly.edu/~hjew/bikelean.html FWIW I used to have pedal strikes all the time when I first got my Romulus, but I don't have the problem any more. I haven't changed anything, so I guess I just adapted.
