Precision Today
There have been many variations since 1969's 'Precision Club'. 3NT is played as 'Gambling' (where it used to show 24-27HCP), 1♣ - 1♦ is not anymore a 4-4-4-1 (Impossible Negative), and the "Unusual Positive" is used instead.
When 1♣ - 1♦ is not anymore a 4-4-4-1,
1♣ - 2♥ = 8+ HCP, 4-4-4-1 Singleton ♠;
1♣ - 2♠ = 8+ HCP, 4-4-4-1 Singleton ♣;
1♣ - 3♣ = 8+ HCP, 4-4-4-1 Singleton ♦;
1♣ - 3♦ = 8+ HCP, 4-4-4-1 Singleton ♥
Also, modern Precision often uses relay bids or transfer responses to 1♣ to both try to make the strong hand declarer and saving space in the auction. Other popular Precison variations on opening bids are using a strong 1NT (14-16 is most common), using 2♣ to show only a 6+ club suit and expanding the possible hand patterns for the 2♦ bid to include the usual 4-4-1-4 and 4-4-0-5 as well as 4-3-1-5 and 3-4-1-5.

“All great art, and today all great artlessness, must appear extreme to the mass of men, as we know them today. It springs from the anguish of great souls. From the souls of men not formed, but deformed in factories whose inspiration is pelf.”
