Again, we need to use all the information available, which was my point. What may be a double for one player won't we a double for a different player.

I could hit a ball to the fence and likely would get thrown out at 2nd. A few of the HS girls I umpire could hit the same ball in the same place and it would be an easy double and possibly a triple.

There are so many different factors. This isn't like baseball's WAR statistic that compares fact and fiction. We need to make a call based on everything we know, not the pretend world. If we know runner X is slow, she isn't going to run the bases the same speed as a sprinter would. The speed of the runner is something we can easily see on the play.

It's not fair to say X hit will always be a double because in some cases it will be a single, and in other cases the same ball hitting the same place will be a double or triple, not even considering what the defense does with the ball.

It's easy to say we should be able to award protection to X base simply based on where the ball is hit, but in reality we need to take factors A,B,C, X, Y, and Z all into consideration. Often times we don't even know each factor until after the obstruction occurs because we not be looking at that factor at the moment the obstruction occurs.
