I think its more likely that there is something in the source data that isn't being accounted for.
I'd look there next. What are the mean, range, stddev of the data in the database? Are there nulls?

This is really weird as it would appear to me that the <PropertyIsLessThanOrEqualTo> and for that matter the <PropertyIsLessThan> are not working correctly at least not on my version of Geoserver, or the Ands are not configured correctly. I get the same results testing via the geoserver app where I loaded a style with the same sld. Cheers, Brad.

Do you get anything? Brad
