Throughout much of the 1990s Glen Jakovich was regarded as the premier centre half back in the AFL, and his battles with Carey were a talking point and a season highlight whenever the Eagles and Kangaroos met. Jakovich was one of the very few players who could match Carey for strength in a one-on-one contest and as a result he was often able to limit Careys dominance. The rivalry gained significant media attention during 1995 when the pair met three times, with Carey being held to a combined total of just 7 marks, 35 disposals and 2 goals. Carey had dominated their encounters in 1993 and 1994, polling Brownlow votes in two out of three games. Statistically, Jakovich held Carey to fewer disposals and goals than any other player could consistently manage. In all they played against each other 18 times-16 while Carey was at North Melbourne and two when he was at Adelaide-first meeting in round 12 of 1992 and last in round 19 of 2003, with Jakovich being able to hold Carey to averages of 6 marks, 14 disposals and 2.1 goals per game. By comparison, in the 188 games Carey played against all other opponents in the same period, he averaged 7 marks, 18 disposals and 3.0 goals per game.
Question: How many more goals per game was Jakovich able to hold other opponents as compared to Carey?
Answer: 0.9
