It seems that this stupid chicane is gone.
That would be good news.
Looking at the points in those years, I wouldn't say they were frontrunners, but as you say, that is probably due to different definitions of front runners. The original post I was replying too said they had always been in the championship hunt.Depends on your definition of 'front runners' I guess. I think if you're competing for podiums on a fairly regular basis, you're at least a front runner.
As for finishing 4th most years,
1991 - 3rd
1992 - 4th
1993 - 4th
1994 - 3rd
1995 - 3rd
1996 - 2nd
Paints a slightly different picture.
