Position glossary
50/50
Use 50/50 to describe a leg position, rather than treating it as another name for the roll itself.
Compare the position
The free Modern Leglock Position Cheatsheets illustrates 50/50 on page 6. Use it as a visual reference for the athletes' legs and body orientation.
The document dates from 2017. Its positional terminology is useful here, but it is not a source for current competition legality.
Entry, position, finish
A rolling entry, the resulting entanglement, and a heel-hook finish are different stages. Keeping them separate avoids making one example sound universal.
