To quote Doug’s website:

Goldplating (over silverplate) is offered for those who prefer it, but it is much more slippery, and as a result sometimes feels larger than the same size in silver. Lexan (polycarbonate plastic) is a very comfortable but less slippery material that always feels the same temperature, and stays cleaner than a metal finish. It sometimes feels smaller than the same size in metal.

My question: does this mean that the rim size that works best for you could shift by a degree or two in either direction, spending on the material used? For instance, I use a DE N102 rim in silver plate - if I were to choose gold plate would it “work” to shift down to 100 or 101? Likewise, if I choose lexan/delrin should I shift up to 103 or 104?

I've found that Doug's Lexan rims feel one size smaller. I find no difference between silver and gold.

Going from silver to gold usually works to keep the same size, but I always caution people not to move larger and try gold at the same time.

Some of my earlier Lexan rims felt smaller because they actually were a tiny bit smaller, maybe .001 or .002". Lexan doesn't cut quite like brass. But for current ones, stay with the same size.

I find lexan to feel smaller on account of increased friction plastics provide on the lips. Silver is better for me because of less friction, as long as the rim surface remains clean. Gold is optimal for me (with the correct sizing) and gives me the comfort and semi-slippery feeling I need to aid flexibility.

I've gotten 2 identical mouthpieces, one stainless and one titanium. The titanium definitely feels smaller.

My preference between gold and silver changes with different rim contours, but I don't perceive it as a size difference. I find I prefer Doug's rims in silver. When I played a Laskey I found I needed gold plating.

A good friend and colleague of mine has a severe allergy to brass mouthpieces, no matter the plating. For years he played one of Doug's mouthpieces with a Lexan rim, but the brass farther down the mouthpiece even started to irritate his skin. Now he plays a stainless steel mouthpiece from Giddings, and in order to get the sound he wants he found he needed to go to a larger rim diameter. I don't know if that's a typical adjustment or not, but the stainless mouthpiece sounds better - and by better, I guess I mean more like a brass mouthpiece - for him than for anybody else I've heard.

I have never found 2 identical mouthpieces, from any maker in any material.

Nor have I.
