Nope. Mooks will often have a 6+1d6 init having <10 is a 50/50 proposition. But init in 5th is just highest score goes first, then the next highest etc etc until everyone has gone (interrupt actions changing the possible order). Once everyone has had their action, it starts again at the top. If your init is <= 0 you don't get an action this IP. Once everyone's init is 0 or less it ends the CT, new init.
