Sorry, it only just hit me, but I think I know where you got the "1.3g" from!! The sheet SHOULD be read as "1 - 3g"!! The printing is terrible and Stanton/Pickering often have typos and inconsistencies in their manuals. Trust me, the nominal is 2g. Try again at 2g (on a non-critical record!!).
If you get a stylus box, they quote a tolerance around nominal rather than a range (and a smaller tolerance at that) - hence I wrote 2 ±0.5g. In general, I find that Pickering and Stanton generally perform best at nominal or higher. I discussed this with John Kuykendall back in the day and he said that they wrote the spec for the 681 as 1 +0.5 0-0.25 specifically, because the performance was calibrated at 1g even if the compliance and tracking ability would allow you to go lower. He advised me never to go below the nominal.

The D2400Q is the same animal but with a slightly wider frequency response range to 50kHz not 45kHz for the D2000Q.

The UV15 was the first CD4 cartridge (the Stanton equivalent was the 7804DQ) but was significantly bettered by the XUV when that was released. The XUV (for which the D4500Q was made) has a nominal of 1 ±0.5g for VTF.

With Stanton/Pickering, the suspension is a tie-wire so you will always be able to deflect the cantilever. The damping elastomer is the part that hardens and you will see the effect of this in restricted tracking ability and a very curtailed frequency response (it will sound quite dull).

Do you have any test discs for setting VTF? The dead give away for a hardened elastomer is if you get no improvement in tracking ability as you increase VTF. You should be able to get to at least 60um (+14dB) within the VTF range.
