6.5 million is a red herring.
6.5 million is
hours not flights (1.4M flights) - but it
is all 777s (in fact all RR powered 777). That does cover several variants however, and fuel tank configuration is different between the variants, which may well be significant.
Of those flights, they've only looked at (only got?) data on 13,000 RR powered 777 flights, and the conditions are unusual within
that set of data.
