Wow. Never thought this thread would get so popular or so heated.
3 quick thoughts:
1). I doubt that many people have 51 inch verticals but those guys are definitely in the upper 40s.
2). I’ve never seen vertical jump measured with plantar flexion in applied settings / field tests. That includes NFL and collegiate combines, USA Bobsled / Skeleton tests, and weight room test protocols of 5 different collegiate strength coaches.
3) From a true test of vertical JUMP you would have to factor in plantar flexion and also do the arm reach to the same extent as one would use in the actual test. The latter is a common ‘cheat’ that people use on tests where the tester is lax.
