Well, I agreed but then I realised that when since it is being stated in the beginning of the log file that it is using the xxx_scale values (even though it's not) it might confuse some people even more than it confused me. In addition the fix_xxx default values aren't in the GUI so you have to start guessing from a blank.
There aren't static default values for wxc and wxu - they're calculated automatically by comparing the gradients for the X-ray and restraint terms. (I forget the exact reference for this.) Empirically the weights tend to fall within a well-defined range, but the values are variable, which is why we recommend using the (slower) weight optimization rather than setting them manually (which can involve a lot of trial and error). -Nat
