It's always interested me that the typical 1♣ opening is 16+, and positive responses are 8+, which means they bid game with all 24 counts. I know Meckwell consider that to be "extras", but most of us like to have at least 25 HCP or compensating shape.
Of course, this only happens when both are dead minimum for their bids. But they may already have upgraded their hands due to distribution when choosing the initial bids: 1♣ might have been a shapely 15 count.
