Same message. One is easy to act on, one isn't.
Flesch can't tell — we can.
Version A (the usual memo)
The new IT-security course is in the Learning Portal. Staff are asked to be aware of it before 15 March. It takes about twenty minutes. HR can help those who need it.

Version B (same facts, clearer)
You must complete the IT-security course in the Learning Portal before 15 March. It takes about twenty minutes. If you need help, ask HR.
Flesch 71.8

Flesch rates Version A as easier (79.7 vs 71.8).
Our action-clarity shows the opposite: only 40% of readers land the right action
in A, vs 72% in B. In Danish, LIX scores the two 22.7 vs 23.1
— identical; it simply can't see the difference.
