Figured we'd get this out of that other thread.. This may be me looking for a simple answer to a complex question, but why are there interpretations of the rules which run counter to the text of the rulebook. Case in point, if a foil fencer makes an attack by withholding the blade, which usually means their front arm is bent. From t.83.4, That seems pretty clear if the arm is bent during the attack, it's prep. What led to the interpretation allowing for a bent-arm attack establishing priority? Note -- I'm not trying to re-hash the age-old argument. I actually want to understand the WHY and HOW this came into being.
