The clock type is the category. Not a 4-week block.

Each format has a different job. Pick one in the generator, or leave it on “Any” and the date will choose.

Format	What it is	Typical window here
AMRAP	As many rounds/reps as possible in a fixed clock.	15–24 min
For time	Finish the work. Cap so it does not become a 40-minute grind.	15–25 min cap
Rounds for time	Same couplet/triplet, repeated 4–6 times.	16–26 min cap
EMOM	Every minute on the minute. Rotate stations.	16 / 20 / 24 min
Tabata	20 s on / 10 s off × 8, then change station.	~20 min
Chipper	One long descending list. Do not rewrite it as extra rounds.	18–28 min cap
Intervals	Repeatable work/rest. Last set should still look like the first.	18–27 min
