Webthe 30-day median slope values are negative or zero, which suggests a minor increase in code velocity. Using a 30-day rolling mean or median is standard prac-tice. Depending on the context, 90-day (quarterly) technical indicators are also used to check for trends. We also calculate the Mann-Kendall and Sen’s slope values as an additional data
