I agree with almost everything that's being said here, except one thing about this 'muddying water' business. To muddy the water, the water need to be clear first. The way I created the T-profile is probably not free of some deviation from the original tracks indeed (we're talking tenths of millimeters here, close to the tolerance level of the plastic extrusion process of both replica and screen-used profile). But at least I am clear about the origin and method. Gino's track is based on scan data, we now know, but he also said that he is not at liberty to share the source and the details. So for him the water might have always been clear, but to the rest of us, it was troubled all along. Now, I don't want to be blaimed of discrediting Gino. I'm not saying he is not speaking the truth, all I say is that the water was not clear to begin with and I wish it was.
