I can't read the chart reference sub-window speed in knots. It's too blurry. Deadload endpseed looks like the speed of a non-powered weight at the end of the deck. Weight is fairly straight forward. To me this looks like the load chart for a carrier's catapult. So many PSI of steam required for an aircraft of a given weight. If I could read the darn sub-window speeds I could probably figure it out.
