That “gradual decline” is an artifact of your maths, in which you're gradually changing the weight of recent years.
Consider a sequence with an extreme drop-off: 100, 100, 100, 100, 40. Taking averages of all the numbers, then all but the first, all but the first 2, and so on, yields: 88, 85, 80, 70, 40. That might look like it includes a gradual decline, but clearly there's nothing gradual in the underlying data.
- do_not_redeem 2y agoRight you are, good catch. Here it is broken down by year then. year rank ---- ---- 2007 80 2008 13 2009 3 2010 1 2011 2 2012 9 2013 78 2014 14 2015 305 2016 363 2017 7 2018 65 2019 28 2020 7 2021 106 2022 353 2023 86 2024 82 I still don't see a step change. 2022 was bad, but not as bad as that slump in 2015-2016.
