Just did a quick test on this on a bee in Ceizek. Hit the bee with stun with no Enmity+ gear, bound it, and then stood first at 25.5 yalms and then 24.5 yalms. Popped on Crusade and then did all your standard RUN moves (Valiance, Vallation, Liement, One for All, Pflug, Swordplay, Last Resort, and Battuta) and one Foil.
From 25.5 yalms the bee turned to my RDM at 52% health. At 24.5 yalms the bee stayed on the RUN until death.
For another quick test I pulled a bee on RDM and then cast Regen on the RDM to get on the hate list. Popped every move at 25.5 yalms and the bee stayed put. Moved to 24.5 and a single Foil brought it over.
I think 25 yalms is the ticket.
