For timing with the plate I went to the southern umpires clinic last year. and my timing was super fast, and one thing they told me and had me work on was when you hear the pop in the mit say to your self like a brand such as Nike or Rawlings. Then once you have done that then you can make your call. So I worked on it and now I notice I'm a lot slower and more relaxed. Not in a hurry to make a call. The best I can say for the bases is that you just look at the whole picture dose he have everything that is needed for the call to be safe or out. Don't focus on just one thing because there is a lot that has to go right for a play to happen.
