There are so many factors in play here. As a catcher all you can do is catch it and throw it. The speed of the runner, the lead of the runner, the condition of the field ie wet dirt, loose dirt, hard dirt, the type of jump the runner gets, how well the pitcher holds the runner, how long it takes the pitcher to get rid of it, the type of pitch curve ball change up fastball, the location of the pitch inside and up outside and up down and in away and up etc etc etc. These are all factors that will determine wether or not the runner is hosed or not. The only thing you can actually controll is how you recieve it and how you get rid of it. One thing for sure is an accurate throw will give you a chance. You want to work on getting rid of it quick and accurately and with as much on it as you can and still accomplish the first two goals. Ive seen kids hosed on 2.3's and I have seen kids safe on 2.0's. Catchers will always be blamed by the fans for not throwing out runners. And they will always get the credit when they throw someone out. The fact is it is a combination of the pitcher and catcher working together as a team. Only worry about what you can controll.
