I had the same thought, and then thought there should be a third 'curve' labeled "Actual Progress" that combines these two. The spots where effort goes down could still drop off, but the climbs back up would be tiny staircases. Being relatively more consistent overall is what matters.

Hills happen; one step at a time.

Same, same, same,... ...which then made the title even more ominous!

🤣👏 Thank you!

I confess: I'm lost. r/whoosh 🤦‍♀️
