Scaling is really dependent on what your initial texture is supposed to represent. It is something only you can know. In addition, remember that when calculating this, most video cards (and I believe it is an OpenGL limitation too) that you are only guaranteed a maximum of 16 repetitions on a single polygon (ie S & T cannot be any bigger than 16.0 for your texture coordinates). If you are doing terrain work, I )highly_ recommend you use Chris Thorne's Rez project code.
