I'll agree with you that your not going to see any wild swings with it, But it started out pretty far to south almost GGEM like a few days back only to slowly tick north.
Not saying that the GFS or GEFS is right, But the euro hasn't been steadfast either, The only flag that i still see is that the 06z EPS took a good bump north too, But we shall see here at 12z.
Exactly what you don't do, You look at all 31, You look at the mean, That will tell by where that's tracking and possibly heading and there are several that are tracking further NW.
