We are based in germany and use 1000ft as standard thrust reduction altitude at any german airport (and elsewhere for that matter). Standard procedure is NADP 2, even in EDDF, which follows standard german rules as mentioned above.
According to my documentation both NADP 1 and Procedure A mention to accelerate "at" 3000ft AGL. The big difference is the lower thrust reduction altitude of 800ft AGL in NADP 1
