I collected data through 100 Jail lvl 1 runs starting from the waypoint. The data was collected to see if Rogue Encampment exit orientation effects Dark One Champion spawns in Jail lvl 1.

The data was collected to see chance of acquiring Teleport in Act 1 on the Sorceress for speedrun time efficiency.

Sample size = 100, Mode = Normal, Online (players 1)

Rogue Encampment Exit Orientation/Dark One champion pack successful spawn Key.

tl = top left, tr = top right, br = bottom right, bl = bottom left. 0 is no pack, 1 is pack.

Instance orientation & success, Total runs.

Totals

tl: 21 instances. Total packs: 4 : 5.25% chance

tr: 9 instances. Total packs: 2 : 4.50% chance

bl: 10 instances. Total packs: 3 : 3.33% chance

br: 60 instances. Total packs: 13 : 4.61% chance

Findings

There was roughly the same chance of Dark One champion packs per exit orientation. My speculation is with a larger sample size(> 100 runs) there will be a 5% chance, so 1/20 runs will you get Dark One champ packs to get efficient experience to get Teleport in Act 1. Bottom right exit had a 60% chance to spawn. Data wasn't collected about distance from Waypoint to the champ pack.
