"Overall, I would probably suggest that you try to understand the trend of the aircraft (shallow/steep) and modify that based on the DME check distances. Little high at 12d, tweak the descent rate, check it at 11d." - When thinking this over again...what if your low at 12dme? then you could risk hitting something? thats why the other mental thinking is better because you decent down to the altitude until the dme then futher decent. thats how I look at it.
