Ok, but did you find anyone 6'6 w/o shoes w/ a 7 wingspan who had a 8'2.5 standing reach?I think that’s on the low side.
It’s not an exact science.
Someone measured 6’2.25 w/o shoes with a 6’8 wingspan and a 8’5 standing reach.
Someone else measured 6’4.25 w/o shoes with a 7’0 wingspan and a 8’5 standing reach.
If one measurement is off, it's fair to question all the measurements.
