It can be put into two categories. The early 1990s and late 1990s. By the late 1990s the grass on centre court was considered harder and higher bouncing, aiding rallying and kick serves. Pat Cash mentioned this every Wimbledon whilst main commentator / analyst for BBC during this period.
That makes sense, both Rafter and Agassi had a lot of success with the high bouncing kick serve during that period from 1998 through 2001. Rafter previously mentioned that the grass beforehand didn't help his famous kick serve on both deuce and ad courts.
