I appreciate the thoughtful reply. Every time I see this list trotted out I can't get past the obvious red flag. Nice to have some more background on it.
So when the JavaScript doesn't type check, the authors measured a different program that does type check.
Even so, that only messes up the results because the mean is used rather than the median, and the data tables published with that 2017 paper, show a 15x difference between the measured times for a single outlier the selected JS and TS fannkuch-redux programs.
That single outlier is enough to distort TS and JS "mean" Time difference.
