That is nonsense. They were using precision scale and those are
usually telling the truth. Of course few gram mistakes can occur, like
one did occur in January, when Levi put an adhesive tape to seal the
valve of hydrogen bottle.
Here however the measured value was 1000 fold too little, because used
amount of hydrogen should have been something in order of 1.7 kg that
was initially reported. Not 1.7 grams.
I would speculate, that the hydrogen consumption was weighted but
there was not data recorded for before and after values. And later
when writing the report bottle weights were taken just from the
previous Oct 6th report and put there, but of course here was made the
blunder that units were not in kilograms. This is far fetched
speculation, but something like that would make some sense.
However truthfulness about the figures is just impossible, because
Rossi has made several day private tests with MW-plant before the 28th
demonstration. Idea that he would use different hydrogen bottle for
demonstrations and testing is not plausible.
