Question about values on Manage Routes screen

[millrise]

This is my first post! I've been playing for about a month and this game is slowly taking over my life.

I apologize if this has been asked before. I've been searching and I haven't been able to find the answer.

On the Manage Routes screen under the values for Avg PLF/CLF, revenue, etc, it shows in brackets how much each value has changed over time. What is the time period of this change? Is it the daily change? Weekly change? I can't seem to figure it out.

Week.

(compare to the route details page and you'll see them match)
