Measures championships won within a player's best 5-year window. This captures peak dominance rather than career totals. A player who won 3 rings in 5 years (like Shaq 2000-2004) scores very high even if they only won 4 total career rings. This factor feeds the Peak Performance Index (PPI) specifically, distinguishing players with concentrated championship bursts from those who spread wins across decades.
Bill Russell won 5 championships in a 5-year window multiple times (e.g., 1959-1963: 5 rings). This is the most concentrated championship dominance in NBA history, far exceeding any other player's peak window.
Jones won 5 championships in multiple 5-year windows, including 1962-1966 where he won 5 consecutive titles as a key player, matching Bill Russell's unprecedented peak championship concentration.
Jordan had two three-peats: 1991-1993 and 1996-1998. Both 5-year windows contain 3 championships as the clear best player, representing unprecedented peak championship dominance. He is the anchor entity at 99.
Havlicek won 4 championships in the 1963-1967 window (1963, 1964, 1965, 1966) and later had another strong window. Four rings in five years represents unprecedented peak championship dominance, rivaling Russell's concentration.
Cousy won 5 championships in a 5-year window (1959-1963) as the starting point guard and primary playmaker. This matches Bill Russell's peak concentration and represents unprecedented championship dominance.
Robert Horry: 7 rings total, best 5yr window includes 3 with Lakers (2000-02) = three-peat plus 2 with Rockets (1994-95). Arguably 5 in a window of adjacent years. Elite championship contributor.
Shaq won 3 consecutive championships from 2000-2002, earning Finals MVP in all three. This is the anchor entity for this factor — a perfect three-peat as the undisputed best player.
Rodman won 3 consecutive championships with Chicago from 1996-1998 as a crucial defensive anchor, achieving the three-peat threshold as a primary contributor.
Kobe won 3 consecutive championships from 2000-2002 as a key contributor alongside Shaq, representing a perfect three-peat concentration in his peak window.
Curry won 3 championships in a 4-year window (2015, 2017, 2018) as the primary player, representing unprecedented peak championship concentration in the modern era.
Pippen won 3 championships in two separate 5-year windows (1991-1993 and 1996-1998), both three-peats as a key contributor. This places him in the three-peat tier alongside other dynasty players.
Mikan won 4 championships in a 5-year window (1950-1954), achieving unprecedented peak dominance as the league's first true superstar and dynasty anchor.
Worthy won 3 championships in a 4-year span (1985-1988), including back-to-back titles in 1987-1988 where he was Finals MVP, representing elite peak championship concentration.

Parish won 3 championships in a 6-year window (1981-1986) as a key contributor to the Celtics dynasty, placing him in the three-peat tier for peak championship concentration.
Bird's best 5-year window (1981-1986) contains 3 championships, constituting a three-peat-equivalent concentration that places him in the dynasty-level peak tier.
Duncan's best 5-year window includes 2 championships (1999 and 2003), where he was the clear best player and Finals MVP in both. The anchor explicitly scores him at 85. He never had a three-peat concentration.
Green won 3 championships in a 4-year span (2015, 2017, 2018) as the defensive anchor of the Warriors dynasty. This concentration of titles as a key contributor places him at the three-peat threshold.
Parker's best 5-year championship window (2003-2007) contains 3 rings as the starting point guard and key contributor, placing him in the back-to-back champion tier.
Reed won 2 championships in a 4-year window (1970, 1973) as the team's best player. Back-to-back championships within his peak window places him in the 72-84 range.
Hakeem won 2 consecutive championships in 1994-1995 within his peak 5-year window, placing him in the back-to-back champion tier as the Finals MVP in both years.
Robinson's best 5-year championship window (1999-2003) contains 2 rings, placing him in the back-to-back champion tier alongside Kevin Durant, though his role was more as co-star than primary leader.
Johnson's best 5-year championship window (1982-1986) contained 2 championships with the Celtics (1984, 1986). This back-to-back championship concentration places him in the 72-84 range.

McAdoo won 2 championships within a 5-year window (1982, 1985) as a meaningful contributor to the Lakers, placing him in the back-to-back champion tier.
Julius Erving's best 5-year championship window contains 1 NBA ring (1983). He made multiple Finals during his peak years but only captured one title, placing him in the single championship in peak window tier.
Billups won 1 championship during his peak 5-year window (2002-2006) with Detroit, placing him in the single championship in peak range as the team's leader.
