Actually, the fact that the TG figures are on a smaller scale than most others, I find to be an advantage. Beyer figures, for example are on a 3 times larger scale than TG. I find this has a tendency to exaggerate the importance of each Beyer point difference, which is really close to meaningless. A full point difference on the TG scale, on the other hand, is much more significant. Showing small differences as small superscript gives me a better picture of their lessor importance than full points.
In fact, when I used to make my own figures I used a a scale very similar to yours in which 1/5 sec. at 6 furlongs was equal to one point, which is very close to your scale in which a length at 5 furlongs equals one point.
