>Obviously you don't use T-graph figs at all and make up stuff as you go along.<

Well, it's hard to discuss these matters with someone with this attitude. I don't make anything up. I use several sources of speed figures and other subjective methods for evaluating performances.

Over the years I learned 2 lessons.

1. Every speed figure maker makes mistakes because of the complexities of the task. So I never assume that the set I view with a religious devotion is always right - even when the result matches the figures.

2. Even when I have the correct speed figures, they do not always reflect matters of pace and other intangible qualities of ability.
