While generally productivity would be a major consideration, the Spiteful added 20-40mph to the top speed of the Spitfire, but wasn't produced after all, in the case of the XP-47F I more curious as to why it lost 7-10mph with the laminar wing installed, given that that was pretty much the opposite of what happened to every other design that had a laminar wing tested on it.
That's what I'm really wondering.
