Game Mechanics: Damage disciplines not affecting non-standard attacks

[Wildas]

Duelist did the following,

2x to all hits and 4x min hit. If 4x min hit was > 2x a normal hit the 4x min modifier would supercede.

However, I'm pretty sure I remember 240 being min backstab with duelist. Old safehouse archive should have some screenshots.

553 was max normal BS with a 15 damage weapon, 1106 max duelist backstab.
