We know of ten events which produced a robust discontinuity in progress equivalent to more than one hundred years at previous rates in some interesting metric. We know of 53 other events which produced smaller or less robust discontinuities.
These cases were researched as part of our discontinuous progress investigation.
This spreadsheet details all discontinuities found, as of April 2020.
