Camshaft question

The way you tell is you advance or retard the cam at the track and that tells you where it wants to be the combo matters
why listen to anyone else thats about as usefull as a sunroof in a submarine
before someone tells me the lsa is ground into the cam everyone knows that as well as what a tighter or wider lsa does
some just will say oh i dont trust that test on there happy dyno yada yada
