Initially

1 - 1 ( or major ) - X - 2 - -- 3+ ; 6-9 total points
3 - Unbalanced -- 4+ ; 5-7 total points

GIB's hand in that case has just 3TP, and it's not unbalanced, so cannot qualify with less TP under that rule as doesn't have singleton/void to compensate lack of points.

Later over 3 things are almost similar, as like bidding 2, so still some TP or shape is not enough.

Looking at only NS hands it seems like good -1 defense, but with Q and J in red suits confirmed by opps, North hand has neither entry, neither extras beside 4th trump.
