I understand what you mean, and yes they could have done a lot better. I could have done it in probably 2 pages (not 26), achieved a better result and been simpler to extract the range data etc. That would mean greater safety outcomes.
If I had nothing to do and was bored I would have a go at it for giggles.
By the way, and I expect you know this but APS is all about critical thinking and application of science and data. The rest is what people think its about.
Cheers!
