Interesting explanation but quite inaccurate. First, spring tar is not a lubricant, it is used to dampen spring vibration. Its not splattered around the cylinder walls for purposes of any sort.
Second, if you were to wait until the piston wears the cylinder out whats the point of lubing the gun? The piston should be lubricated with molybden disulfide paste, or moly paste, to prevent such an occurance. Once applied, it should last a few thousand cycles before it needs to be done again.
Most newer guns have synthetic seals, so chamber lube isn't really required. However, older guns with leather seals need a couple drops of silicone oil through the transfer port once in a while to keep the leather pliable.
