Wouldn MOND effects show up in precision solar system tests?
They may have already. Whether they should or not depends on the interpolation function mu(x). The accelerations in the inner solar system are millions of times higher than the MOND acceleration scale, so all that can be tested here is the (slight) deviation of the interpolation function from unity. This might be perceptible if mu(x) approaches unity slowly in the limit x >> 1, but would not be if it converged rapidly. For example, if mu(x) = 1-e-x, then the deviation one is looking for is of order one part in e108.
