It depends are you doing it for yokes or mirror fixtures.
Yokes do figure eight, if you use circle and the tilt goes between positive and negative values of tilt. It happens when when size of tilt FX is big enough and the base value is suitable.
If I remember right, when using mirror fixtures figure 8 is pan using sin and tilt using cos (sin+90°) at half speed compared to pan. I think it works also with yokes, but only if tilt doesn't go between negative and positive values.
I might be totally wrong, cause I had no chance to test this...
