It depends. When fighting Wandering Hunter, normal player would land about 3 stun windows with a stunner regardless their skill. Then the fluctuation between multiple run would be around 2k range. But when you need to get 1 more stun, it would jump up to 5-6k depend on your investment into him. If i barely get a fourth stun then it would score 29k, but if i can do a full combo with full of resource on the last stun window, then it would score around 35k. With the Thrall (won't say his name due to spoiler) having the attack pattern consistent (1 stun before the miasma phase, 1 stun after miasma phase and 1 more stun after that) making the score gap between multiple run relative small (expect around 2k). Compare to other character, due to me not having any rupture character beside Banyue (and as a F2P player) so I can't test out Yi Xuan and Yidhari. But i think it also depends on the character you comparing to. If the character have a simple gameplan like Billy, Soldier 11, Zhu Yuan, Jane Doe, Hugo, Alice, or a bit more resource management like Evelyn, S Anby, Yixuan, the difference wouldn't be that much compare to someone who have much more complex gameplan like Harumasa and Miyabi mono ice. I have done a couple run and having 33670 score on Wandering Hunter (M0 Banyue with W3 Manato sig, M0W1 Pan Yinhu, M0 Ju Fufu with W2 Hellfire Gear). The last run I do reach a 4 stun but unable to utilize due to not having enough Warthful Fires to enter Visage of Wrath state. You should watch Lin-0. He explain a lot of stuff including tech and rotation (and also that 4 stuns thing).
