Then what should be the ruling? if with the given explanation most of the players lead S, that indicates N made a popular lead which got punished due to misbid and/or misexplanation. Should NS get +13 instead of -13 because of that?
From this poll result, we can not infer that most of the players would not lead a spade if the 3 spade bid would have been explained as spade stopper asking. May be we need a general poll providing the lead options for different explanations of the 3S bid.
Yes thats not logical...since you have already given your support you can force by doubling ( with bal hand) or you can bid 4H with unbal hand...but we had a generic agreement thar all voluntary 4m bids are F..
