add delayed time in css3 animation

I just set an animation to a div and it succeeded. Now I want to get it proved because its delay is too short! so how can I add the delayed time between animation (0% to 25%) and animation (25% to 50%) here is the code:

#flow{
      position:absolute;
      -webkit-animation:mymove 10s ease-in-out;
      -webkit-animation-iteration-count:3;
      -webkit-animation-delay:1s;
     }

@-webkit-keyframes mymove
    {
       0%{left:5px;}
       25%{left:127px;}
       50%{left:249px;}
       75%{left:371px;}
       100%{left:5px;}
     }

everyone!Thanks for your attention !I have found the answer but I don't know the Api of the definition of percentage in keyframes!And if you know sth about it ,just give me a hand ,thanks a lot!

@-webkit-keyframes mymove
{
   0%{left:5px;} 
   25%{left:127px;}
   26%{left:127px;}
   27%{left:127px;}
   28%{left:127px;}
   29%{left:127px;}
   30%{left:127px;}
   31%{left:127px;}
   32%{left:127px;}
   33%{left:127px;}
   34%{left:127px;}
   35%{left:127px;} 
   50%{left:249px;}
   75%{left:371px;}
