To clarify, me and my partner tot it was in, but the opposite player thought it was out. During the discussion, the OP said that "when the shuttle lines partially on the line, it is considered OUT under the new scoring system... (implying that under the old scoring system, it was considered IN)".
And he even backed it up by saying another long-time session of his... plays by this rule that "landing partially on the line = OUT", so it must be correct.
Eventually they suggested a let, but I was damn shocked that a basic rule like the above can be misinterpretated. I understand that we are playing a social game with no reputation or monetary rewards at stake, but I feel emotionally charged and compelled to act then, esepcially when a basic regulation like this is not adhered upon.
1) Whose understanding is correct?
2) If mine is, what should happen in future games if a similar scenario occur?
To the OP (if he is reading), like I said... it was not whether that particular shot landed onto/partially/off the line, it is to clarify matters so that a proper game of baddy can be enjoyed.
