Danny Kleinman points originate from a September 2001 Bridge World letter from Doug Bennion of Toronto. Bennion's research looked at a new pointcount called Little Jack Points (LJP). Bennion counted A=6.5, K=4.5, Q=2.5 and J=1 as his research showed this better reflected their relative values than the traditional 4321 valuation. He then added .5 for any two of these cards working together in the same suit (except a QJ combination). To transform the result to a scale that we recognise multiply the result by 10/14.5.
Danny Kleinman's version more closely reflects the judgement of Edgar Kaplan in his 4C's (Bridge World October 1982) article.
 Count A=13, K=9, Q=5, J=2 (double Bennion's values)
 Add 1 for a 10 accompanied by exactly one 9 or higher honour
 Add 2 for a 10 accompanied by two from 9 and higher honours
 Add 1 for each suit headed by A or K and exactly one other picture card (i.e. suits headed by AK, AQ, AJ , KQ , KJ)
 Add 1 for each suit headed by AQJ or KQJ
 Add 2 for each suit headed by AKQ or AKJ or AKQJ
 Subtract 1 for unguarded picture cards (i.e. singleton K, doubleton Q (with no higher honour) or tripleton J (with no higher honour))
 Subtract 1 for any suit whose lowest card is higher than a 10
 Subtract 2 for a 4333 distribution Divide the total you have by 3 to get the equivalent HCP, say n HCP If the total divided exactly by 3 you have a bad n HCP hand, if the remainder is 1 you have an ordinary n HCP hand and if the remainder is 2 you have a good n HCP hand
 i.e. 45 points is a bad 15, 46 points is an ordinary 15, and 47 points is a good 15.
 If you work through the steps there are no net adjustments for doubleton honours except QJ where you subtract 2 (one for unguarded Q and one for lowest card higher than 10)
Example of end result : 8 (a poor 8) , 12 (an ordinary 12) , 15+ (a good 15).
