The DCR begins to rise and eventually meet the SCR as rpms increase and the engine approachs 100%+ VE. Above that the bleed off of a large cam doesn't have enough time to affect things as much. Reversion is almost non-existent at that point.

ie, don't go crazy thinking SCR is low enough in a calculator. Real world at high rpms will see a completely different story. Don't forget quench can help or hurt detonation as well.
