P7 Measuring Time
I've no idea who came up with Stretch and Shift as terms for measuring time. No one in my (reasonably extensive) group feels that these are either intuitive or thematically inclined. Short and Long are far more understandable as are Short Rest and Extended Rest - there are so many more meaningful / memorable options. Perhaps Shift and Stretch are just phrases that are more popular outside of the UK. This is a personal issue rather than a failure in the rules so I'm sure there are plenty of people who are absolutely fine with those words but I scrapped them immediately
