I think a better assumption would be that the Boyle's ceiling be taken is the deepest ceiling at any point in the dive.  This gives very nearly the same result for a square profile dive, but in a multilevel dive such as your example, the decompression time would increase with the deep bounce, as one might expect.

I thought you had already sent a patch for this. BTW, the thread that I got the idea from to look at this was about MultiDeco which (due to a bug apparently) gets the bounce dive really wrong.
