Yes and no. It's a lot in the sense that we are way off from what we believed or knowledge to be. But on absolute scale, it's not a lot. The current determination of the Rydberg constant puts it at 10973731.568160 1/m with an uncertainty of 0.000021 1/m. So a relative precision of ~2*10^-12 (or maybe only 10^-11). The standard acceleration of gravity is, btw, defined, so no uncertainty. The gravitational constant G is known only to 10^-5 or so.
