There's been some question about whether the new Saturn flipper "rubbers" are larger than normal, and thus would change the flipper gap and other things like that. So I'm not a scientist with a lab, but I did get a couple orders of the neon Saturns, I have some spare "normal" rubbers lying around, and I own digital calipers, so I did some quick checks. In all cases I tried to keep the same amount of pressure on the caliper jaws, the results should be pretty accurate.
First up the normal rubbers, which are blue and yellow (note that they were not exactly the same, there's some variance) 3.83mm and 3.97mm:
