Basically transforms the "0.25x - 0.50x - 1x - 2x - 4x" options from the in-game menu into sliders spanning from 0.1x (10 times the length) to 10.0x (1/10th times the length) of each age groups.
It will not work from the lobby, but once into your game, head into the Options > Simulation, and you will see the new sliders. The game seems to auto-round to the NEXT closest integer (full number), so that if say, the young adult group lasts 27.72 days or 27.05 days after your percentile setting, it will go to 28days. A bit of trial and error, but it is LEAGUES better than the old options and will allow for much more precise control over said age groups.
-- Enjoy !
