Description

It requires a careful look at the code, but it may be wrong, because it was mimicking old GHC code and there apparently was a bug in that code: https://ghc.haskell.org/trac/ghc/ticket/12424

Research direction

Locate the code that calculates elapsed productivity for the bottom pane and trace how its inputs are derived. Read the linked GHC ticket 12424 to compare the suspected behavior with the reference bug. Done means determining whether ThreadScope reproduces the issue and correcting the calculation if it does.
