where to install a tonearm

Hi, Until today I always thought that all that I need to set up a tonearm is to use a protractor to find the "pivot to splidle" distance and that's it. If I want I can draw an arc with this information and I can install it anywhere in that arc.
I have a Lustre GST-801 to install and in the manual found that besides showing you the correct distances, they include 2 more measurements: they draw a line that goes from the center pivot up to the point when it connects with the extension of the horizontal line of the spindle (basically where both lines meet in a 90 degrees angle). in the Lustre, those distances 199mm (horizontal) and 105mm (vertical). If I take this into consideration the arm will be too close to the platter (my TT has a peripherial ring) and that's not practical for me.
knowing that a platter is round I always though that we can install the arm anywhere in the arc line that I mentioned before ... am I correct?, am I wrong?, please help me with this, Im really confused.

Hi Schubert (the family of?), You mean that the super
intelligent lefthanders adapt and improvise on the
right side of the plinth. There is namely no left side
to adapt to or improvise with. Except of course when the
plinth is turned around with the cover on the front side.

Hi John, What about us? The most are right-handed so the
'normal' arm position is already determined by the TT
producers. Or should I say plinth producers? I have seldom
seen plinths with sufficient space for a tonearm on the
left side of the plinth.
So Jorsan if you are left-handed you are in trouble. That
is to say you need to order a special plinth by Vetterone
and those ain't cheap.

Hi Schubert, This is called 'assimilation' (aka 'the majority rule') while you actually confirm that the rule works. In 'good old days' the kids were forced to behave
'normal' and use their right hand. At present, in particular in Holland nobody knows anymore what 'normal' means. So even two lefthanders of the same gender are
allowed to marry . With each other that is.

Hi John, I already thought that your are a genius but because of my envious character I reduced your genius to the tonearms only. As far as I know nobody ever thought about even the possibilty of an headshell with the fingerlift on both sides. I also thought that you are Englishman and not a Dutchman.You should check your ancestors.

Hi Schubert, Because of my ,say, Balkan jokes the
Dutch never invited me for a dinner so I don't needed
to do the dishes. And then I am sure that I have just
one dad but if I could do without him I would prefer
this state of affairs if this was possible.But alas my
mom was not the holy kind of a person.
