ANSI 104 Ian X1

24 October 2016

At the time of writing it is THE BEST performing ANSI computer keyboard layout, as measured by KLA with Den's scoring (and with only some tests done), as well as second best as measured with Patrick's scoring, across all tests. Den's scoring is more accurate than Patrick's for these sort of layouts, which use unconventional key actions.

By comparison, the current average scores (at time of writing) for this vs other well-known (and not-so-well-known) layouts, as per Den's scoring:
