ISpatialFilter SpatialRelDescription find points not in polygon

Question

Hi there,
I have a point featureclass (not M or Z aware) and a polygon.  I want to use a spatial query to find all the points not in the polygon.  As far as I can tell only the spatialRelDescription will do this.  The problem is I get inconsistent results.  Some points are found as expected other are not.

I used the following string:
"F********"
"******T**"

It finds some of the points but never all of the points.  I am somewhat perplexed.

The alternative is to loop through all the point and use a relational operator but that seems like it would be slower.  The SpatialRelDescription should work.

I am using SP2.  I am probably going to be stuck at SP2 for a long time because NIM074169 has been declined, the solution being: "Use SP2".  I hope this is not the solution for 10.1 or we will be permanently stuck and 10.0 SP2.

What version of ArcGIS are you using? There is a bug in spatialRelDescription at 10.0 that is fixed in 10.0 sp4.

Thanks again Neil,
I am doing it on the featureclass level to delete unwanted points in the featureclass and I have some attribute criteria along with the spatial constraints.  The code is called inside of arcmap but also in an exe.  Reversing the selection would mean also reversing my attribute query.  There shouldn't be more than a few hundred points meeting the attribute constraint, so I think I will just use the Irelationaloperator.disjoint on each point.  Not the most efficient but probably easier to support in the long term.  
I just find it annoying that the spatialfilter spatial relationship enum is very limited and the shape comparison language is poorly implemented.
