The missed approach point is defined by LMM. Hence, a timing DICEY inbound is relevant only to a calculated decision point prior LMM, since you would have a hard time losing 1500 feet AGL in 0.5 nm from overhead LMM to the threshold. Or if LMM is unserviceable.
The timing table is from DICEY to the MAP. Many of us had only one ADF receiver and were prohibited from tuning away from the primary NDB.
