See JaWoodle just did this POI, kind-of with stealth too. It's a two-parter so we don't yet know how the last part plays out for him.
Apparently he's playing on insane, where I just play the default. He's in the wasteland and I was in the snow. He's 7-8 levels higher and had both stealth skills at 5, where I had them at 4. We both have Parkour but I wonder if he might have more of it. He's certainly more adept at using it than I am. His assassin armor is 6, 6, 5, 6 and no night vision, where I had 6, 6, 6, 6 with night vision. He's crossbow, silenced 44 magnum, and grenades with a willingness to cause explosions. I was compound bow with TAC Rifle, shotgun, and silenced pistol for the "oh shaving cream" moments, but didn't need them.
He's not used to stealth play (by his own admission) and is a bit hyper. Some might say that's an understatement, but he's a pro and can obviously handle more than I can, which I probably why I'm more methodical. He played the first third with a helmet light on and wearing the wrong helmet, so his stealth numbers weren't as good as they could have been. Still, he does manage to run off and lose some Z's, so he's onto the technique.
