is that the efficiency obtained by the Wright Experience, for the alleged 1903 66% efficient propellers, varied between 75% and 82%. The team could not get that 66%.
What don't you understand? The Wrights figured 66%, yet the team achieved 75 - 82. When I did maths 75 - 82 was greater than 66. That is, the props were more efficient than the Wrights believed with their 66%.
