"Small changes yield significant outcomes on any frame’s geometry chart. Altering tube angles by only half a degree can dramatically reposition a rider on the bike. Or change its steering performance and terrain interaction. "

Disagree, with repsect. Half a degree is worth about 5-6mm on the front-centre or saddle setback, it's a minor tweak that most of us won't notice and tolerences in mass production might vary that much. And head angle is one part of steering - fork offset and weight distrribution are equally important. Difficult to simplify/generalise when you're looking at a combo of HTA, fork offset and overall front-rear weight distribution, stem + bar dims, etc. In short we shouldn't fixate on a number and should try to get a feel for how well balanced the total geometry is.
