You are the one that doesn't seem to understand MLB's system, after all you are the one that was quoting the old system's numbers until I corrected you. Now you want to pretend to be an expert on the technology. You aren't.
Feel free to pretend the QuesTech system is the best system available and keep using old QuesTech stats to show why using technology to call balls and strikes is inadequate. You can use 2002-2007 figures while the rest of use the 2012 Pitch F/X numbers.
It is clear that the technology has improved a great deal over the last decade and every indication is that it will continue to improve. This means the league has the tools they need at their disposal to make the switch to robo-umps if they decide to make the move. It is not accurate to claim that it can't happen because the technology is not up to the task. If MLB wants it to happen a highly accurate system could be implemented very quickly.
