Just finished reading the report, and it depicts a situation I'm sure most of us can recognise.
On a technical note - and I'm sure HC can help with this - could the lack of a 100 ft call be attributed to filtering due to rate of descent? I can't find a reference in the MK XXII product spec, but I do know that convential AVADs will recognise high Rates of Decsent associated with deck edge crossing and suppress the calls. At 200 ft the RoD was only 1000 ft/min (only in the context of this question) but perhaps by 100 ft it had reached a significantly higher value?
Regardless, even at 1000 ft/min it takes 6 seconds to impact from 100 ft, factor in surprise, recognition, pilot response and then aircraft response, and at best you'll have another Fulmar 76, and at worst, no difference to the actual outcome.
