Where are J K Lewis' piece values, Joe? It helps to familiarize with Ralph
Betza's 'Ideal & Practical Values I-VI'. How many years went into those 2001 articles, now a covenant? Later lists just build on Betza variables from 1990's and 1980's. However, Betza likes to compare pieces pairwise not whole CVs. In system to point-count entire game, available so far are elementary (1) Use unit Pawns 1.0, or 1.1 (2) Where practicable, Rook value & up, ignoring the other pieces, put piece X on empty board with 2 Kings and opposite-colour Pawns, and shuffle them around until finding Pawn-equivalence. These end-game positions are Joyce's  reproducible 'many positions' versus '1 specific position'.  Who should win to left? Trying 10, or 30, positions, we are interested in typical not 
 __ __ __ __ __ __ __    extreme cases with few pieces/pawns. Its experts
 __ __ __ __K__ __ __    know who wins, but move one or two Pawns at a
 __ __ __ __P__ __ __    time one or two spaces, and it goes the other
 __ __P__P__ __P__P__    way.  Pawn Equivalence, Rook = 5.0. There are
 __ __ __ __ __ __ __    in mad-Queen (40+40 points)/ 64 squares
 __ __ __ __ __ __ __     = 80/64 = 1.25.  Should we always distribute
 __r__ __ __k__ __ __    points so that there are approximately 1.25 
 __ __ __ __ __ __ __    the number of squares? So CVs may be like Bridge
hands: the total point-count for bidding in system of all four 13-card hands includes 40 high-card points plus short-suit counts of 5 or 10 or 12 more: 52 points/52 cards = 1.0.  [Whole history of Bridge postdates Capablanca Chess]
