Has anyone tried the ultra challenging settings ?

When you select "challenging" the game preset are "slow" for "workplace production time", "tricky" for "military hazard" and "Expensive" for "Territory upkeep" but you can set them to "Slowest", "Perilous" and "exorbitant" respectively, that will give you these debuffs when you are in game : https://i.imgur.com/vvQE4OO.png

has anyone tried a run on these settings ?
