...and if they promise 8+playing tricks for their "strong" 2
♣, and have it marked on their card, and explained, then they are:
- playing a legal "strong, artificial" 2
♣ according to the regulations and tech notes, and
- opening AKQ-ninth and out 2
♣
The "how weak can a Precision 1
♣ be" is a canard: the regulations on whether a strong club is legal, and how few HCP whether a strong club announced as "Precision" can be, are different from a "strong, artificial" 2
♣.  I can play a strong club 13+ if I want (and have.  The followups are somewhat GCC-constrained :), and open 6 controls and out 1
♣ and have it not be a psych.  But I can't call it Precision, either on the card or as part of an explanation.
This quote is from the Tech files available from Google search, but I just checked on the latest version of ACBLscore, and it's still there and identical.

Opening an artificial and forcing bid without an "abundance" of high
     card values is acceptable under the following circumstance: IF, IN THE
     VIEW OF THE BIDDER, THERE IS A REASONABLE CHANCE FOR GAME IN
     HAND WITH LITTLE HELP FROM PARTNER.
 
     The following hands would qualify:
        S  AKQJ109765       or
          H  754
          D  2 
          C  ---
     
        S  AKQ1098
          H  J109876
          D  4
          C  ---
     These hands may be accepted as artificial 2 club openers IF THE
     OPENING BIDDER THINKS THEY ARE REASONABLE.  On the first hand opener
     needs only one trick from partner.  On the second hand, two small
     spades and a heart honor probably would be enough to produce game.
     What is NOT acceptable is the use of a strong, artificial, forcing two
     holding the following hand:   
                                   S  6
                                   H  2
                                   D  QJ109876542
                                   C  5
     There would be good reason for a director to conclude that the opening
     bidder's prime motive is to confuse the opponents rather than to reach
     the right contract constructively,  It is clear that opener is
     psyching what is ordinarily a well defined bid in an attempt to
     intimidate the opponents.  This is exactly what the rule is intended
     to prevent.
     If a pair thinks that Examples 1 and 2 are two club openers, then
     their convention card should have some notation about playing strength
     in the appropriate place.  Also, if a pair marks their card with HCP
     limits for their two club openers, they should note if it only refers
     to balanced hands.  (Directions - April 1992)
