Sorry, when you start to clear a full flood mask (a mask without a drain valve in the nose pocket) you don't look down first. Apply pressure to top of mask and start to clear while looking up. If the mask has a drain valve in the nose pocket then you look down and start the clear. I was a PADI MSDT for 15 years. I know things might have changed, but the ways I've described have worked for years. (even before my time)
