Just a couple of things. One, if there is a bunt the PU has responsibility regardless which line he bunts it. Two, the PU shadows R1. As soon as he is out the PU will drop step and head back towards the 1st base foul line.
oAfter reading your OP and then your responses to people calling you out, I've come to the conclusion you are a SH*# stirrer. If you ever played you were the type who would start crap and then when was called out on it you would say I didn't do anything. Whether you realize it or not you had 2 strikes against you from the start. Tennis shoes and a clipboard. You are on a very, very, very short leash.
If I'm not mistaken the definition of a Foul Tip was changed sometime before the season started. Now as long as it hits some part of the catcher, some part of the body or equipment, and is then secured in the hand, hands, or mitt it is a foul tip.
