Every flogger plan on the site is written in TheDuchy Knot Notation — a shorthand we created so any two builders can describe the same flogger the same way.

The Flogger page has a four-step interactive guide that covers the abbreviations, the formula syntax, an end-to-end build walkthrough, and the rope-consumption tables. Pause this lesson, work through the guide on /floggers, and come back when you can read the example formula without checking the legend.

If you can answer 'what does 6s – 2FRK6 < HHH < MWK6 > F6[ (3)BK2 ] mean?' you're ready to keep going.
