Quick Quiz
Can you provide references to some of the other formulas? You mentioned ROP and some other more sophisticated formulas. Where might we look for those?
Hi Raymond,
I once, long ago, taught a course that went into detail including many formulas for sparing calculations. I have not been able to find my course notes or binder – might be in the attic… I’ll keep looking.
I do recall that at the time there wasn’t a good reference book available. That may have changed, and I’ll ask a few folks I know that focus on sparing and related practices.
cheers,
Fred
