I just checked the .edu and the animations are already set to 0 (the fastest unless negative numbers work?)
You can try putting the zero to a negative number;
Code:
stat_pri 10, 2, elven_arrow, 190, 35, missile, missile_mechanical, piercing, none, 0, 1
They can be adjusted in the modelsdb file slightly I think much like the edu, and of course the animations files. You can even remove the animation entirely in the skeleton file (it is just lines of code for each animation) and replace it with an existing faster one (I just did for the diplomats bowing, was slowing down turn times by 5 seconds with all that bowing). None of this is basic stuff though plus you need the unpacked animations or unpack them yourself.
