So funktioniert es

FORCAST was developed in 1973 by Caylor, Sticht, Fox, and Ford specifically for technical, non-narrative writing (forms, manuals, instructions).

It uses a 150-word sample and counts single-syllable words: 20 − (single-syllable words / 10).

It does not require sentence-level analysis, which makes it ideal for evaluating bulleted or fragmented text.

20 - \frac{s in g l e S y l l ab l e W or d s _{150}}{10}
