Balkanhawk,
Yes that's the way I understood it. What makes even less sense is that for performance A the minimum approach climb gradient for certification is 2.1%, yet the standard MAP gradient is 2.5%, there is no guarantee in either class that you'll be able to achieve the MAP gradient with one engine inoperative. That said, these figures are certification minimums and the performance of your aircraft could be considerably better - there are some performance class B aircraft with higher performance margins than some performance class A aircraft.
The point I'm trying to make is, study the performance data for the aircraft you'll be flying and understand what it can do, especially if you'll be flying into somewhere performance limiting.
