my highest is 43" but that was a local wall that felt nice too tap. some times you can just feel the right timing etc.
this is two pedal strokes away, i know some people pedal at it, roll abit and then 1 stroke into tap, others bunny hop tap, some do 1 stroke etc.
ive no idea what i average at, only measure what i think is high, if i think i an get it ill just keep trying til im happy (Y)
