I'm in a rush and so haven't yet read all the responses.
MY understanding is that as things worked out he landed within 100kgs of the final reserve you are speaking about. He mentioned several figures to me and I may not have completely understood him but something like 1900kgs, and he said it was 1200kgs for a radar circuit.
Seems awfully tight to me but he did land with just about company minimums.
