To expand further, the inverse square law applies in mechanics.
Therefore you reduce the mechanical inertia (tendency to not move) the nearer to the pivot point you can get it.
The arm can react more quickly to the squiggle of the groove, or more exactly the arm/cartridge can trace the groove more easily.

Mines on about 1.6 I'd guess dave... I dont have scales

No, not just blind guess work, I balance it by eye, set the counterbalance to zero then use the weight scale on the counter balance.. I might be a bit plebby but I don't just wack it on any old how

Having raised this very question myself here on AoS recently, I concluded that whatever works best in practice represents the correct answer. Ignore all of the science and decide for yourself. I find that a lighter weight hung out further on the back of the Jelco works better than a heavy one closer to the pivot. You may conclude otherwise, but you'll have a bit of harmless fun getting to the conclusion.
Shuggs is exactly right.
The bottom line is, the proof of the pudding is always in the listening, even if the results heard don't meet with 'scientific facts' or 'perceived wisdom' - all that goes out of the window if your ears tell you something else!
As for what Chris wrote earlier:
Absolutely true, however the former is only of benefit to medium and high-compliance cartridges. It's a distinct disadvantage with low-compliance cartridges such as the DL-103, SPU or Shure M3D.It reduces the effective mass of the arm, and also lessens the mechanical inertia.
