Very thorough test, with the interesting assertion that the 650b wheel is 'somewhat outdated'. As i've found, tyres from major brands are mostly 47mm, suggesting that this wheel size is generally destined for rougher parcours.
I think 650b was pushed to allow bigger tyres over 700c in most frames but it has been slightly killed off by all the new gravel bikes coming out with clearance for 700c 2"+ tyres.
