Average winning score, Masters, 2002-2008 (after major lengthening and modifications): -7.71
Earlier in the thread, Shivas suggested what has been missing in recent Masters has been the dramatic moves both up and down the board, or what he calls the Beta factor. Others (me included) have suggested what's missing is the ability of a golfer to make a charge, i.e, a sustained sequence of under-par holes.
Question: Are our views of Augusta largely formed by a (roughly) 12-year period (1990-2001) that saw both historically low winning scores and drama of the highest order (the Faldo-Floyd playoff, Woosie's putt on 18, the Couples-Floyd duel, Crenshaw's ode to Harvey, the Norman collapse/Faldo charge, Tiger's historic 12-stroke win, the O'Meara/Couples/Duval shootout that also featured Jack's front-nine charge at the age of 52, the Olazabal-Norman duel, the Tiger/Duval/Mickelson shoot-out)?
Second question (I don't know the answers): When did players move from persimmion to steel/titanium-head drivers? When did ball technology (both length and the "straighter" ball) really take off? Was it sometime during the 1990-2001 run of historically low scores at Augusta? Did technology in effect catch up to Augusta sometime around 1990, and eventually lead to the changes that the Masters committee thought it had to adopt prior to the 2002 tourney?
One other interesting set of numbers: Hogan's 274 in 1953 (when he was at the absolute peak of his game) and to a large extent Jack's 271 in 1965 (when he was at the absolute peak of his game) are arguably historically anomalous scores. Hogan beat the old scoring record by five shots, and no one (other than Palmer's 276 in 1964) came close until Jack in 1965. Between Jack in 1965 and Tiger in 1997, only Floyd (playing the last year I believe in which the greens were bermuda) in 1976 matched it (in a tourney he won by eight shots), and only Seve in 1980 came within four shots of it, before Tiger.
