They aren't quite interchangeable. Both are used in the test suite, with no indication of why one or the other. I think we'd be best off being consistent. Based on the names, I think `_calculateFormulaValue` was intended as a private, or at least internal, method, so favor `calculateFormula`. I do not intend to rename or re-categorize `_calculateFormulaValue`, just remove its usage when it isn't clearly warranted.
