If the wiki is wrong, you could correct it. If the wiki isn't wrong, there aren't stacked effectiveness penalties, only one. (same goes for you, persain). The way the wiki is currently written, there is only a penalty for opping into fort, no penalty for opping out.
Assuming the wiki is correct:
4*2.17*1.21*1.03*.9=9.73. 6.3*1.57*1.4*1.5*1.1*1.03=23.5*.5=11.76
11.76 tpa vs 9.73 tpa. Offhand, it wouldn't surprise me if the halfer were able to steal effectively, and my understanding is that's what they're doing.
