The profile transitions were smooth, imperceptible to the eye. Probably ruled lofts between planform breaks. We measured the inboard end just outboard of the fillet, the separation for the 15/18 extension, and the tip of the 15/8 extension. We might also have measured in the vicinity of the inboard planform break, I don't recall. Edit add: The washin/out transition was pretty subtle, but it was quite clear when the light was just right. Edit add: We only measured one wing. But with the CNC'd Streifeneder molds, they are likely very symmetrical. --Bob K.
