  * <p>The standard version of the metric complies with McCabe's original definition [3]:

- * <ul> <li>+1 for every control flow statement ({@code if, case, catch, throw, do, while, for, break, continue}) and

+ * <li>+1 for every control flow statement ({@code if, case, catch, throw, do, while, for, break, continue}) and
  * conditional expression ({@code ? : }). Notice switch cases count as one, but not the switch itself: the point is that
- * a switch should have the same complexity value as the equivalent series of {@code if} statements. <li>{@code else},
- * {@code finally} and {@code default} don't count; <li>+1 for every boolean operator ({@code &&, ||}) in the guard
- * condition of a control flow statement. That's because Java has short-circuit evaluation semantics for boolean

  * <p>Version {@link CycloVersion#IGNORE_BOOLEAN_PATHS}: Boolean operators are not counted, which means that empty
