I don't think you misled anyone who has personal knowledge of water checks, your observation was made at the very best condition of determining how much water might be in the tanks. If a water check was carried out in sub-zero temps and there was water in the tanks which might have frozen perhaps it would have not been possible to drain any fluid as the ice would have been at the base of the tanks. When the
G-MMMY engines were started there was evidently enough liquid fuel being supplied to the engines not water.
