This layout was developed based on a design by Den, borrowing ideas from Arensito. It's an evolution of the AltGr 1 and AltGr 2 layouts.
At the time of writing it is THE BEST performing computer ANSI keyboard layout for all tests on this site combined, as measured by KLA using Patrick's scoring. On Den's scoring,
with only 11 tests done, it currently ranks second after X1, which is itself a further evolution of this layout.
