Interpreting the sources,( I haven't tested as it's kinda obvious)
 the animationtime is (latest - first - offset) * timemul
If you want to control this equation the simplier is to make its variables constants:
posing timemult=1 offset =0 and first=0 give use animationtime =latest
so have complete control with only one parameter
NB: first must always reset at each update to prevent its auto update in apc
