Note that as all logarithms appearing in the formulas for c1 (t) and c2 are positive, so c1 (t) and c2 are positive.
In addition, new formulas are required for each design.
Of course, in more general groups similar formulas exist, but we have to introduce the derivative of the group operation.
An inspection of the arguments mentioned at the end of 3 shows that the analogies of formulas and are still valid.
The near-sacred statistics are explained; formulas are given for mysteries like the earned run average.
The first two of these formulas have their usual interpretation as negation and material implication.

Instead of exact formulas, one can use asymptotic information.
