Mr. Dowd strongly implied that any versions of the process after TGRA were void and null, or at least I infered it.

Let's run the numbers again using the 1.25/1.30/1.35 multipliers

First Gen CRX: 91 * 1.25 * 17 = 1935 (OW: 2130) Pre-add error: 195
"Newer" Golf : 115 * 1.25 * 17 = 2445 (OW: 2350) Pre-add error: -95

Now that imples that a CRX with it's poor torque and much smaller brakes has either a suspension or other advantage that requires a 290 pound weight advantage for the Newer Golf.

First Gen CRX: 91 * 1.30 * 17 = 2010 (OW: 2130) Pre-add error: 120
"Newer" Golf : 115 * 1.30 * 17 = 2445 (OW: 2350) Pre-add error: -190

Darn, thought we had it when the CRX weight increased, but so does the Golf. The CRX is a 310 pound better car now.

So, let's take the highest multiplier for the CRX - 1.35 and the lowest for the newer Golfs (1.25) ...

CRX: 2130 (OW) - 2090 (Pre-adder weight) = 40 pounds too heavy
"Golf": 2350 (OW) - 2445 (Pre-adder weight) = 95 pounds too light.

So, the difference between the two translates into throwing 135 pounds onto the CRX. Let me see... both are FWD cars so it cannot be that. Torque? I'd say advantage Golf, but let's call it a draw. Brakes? Obviously I need to talk to someone because I fail to see the advantage of rear-wheel drums over huge rear discs. Suspension? Nope.
