[thredds] offsetsGreaterEqual

Hello,
I am running the latest stable versions (as of May 20, 2013) of Java (1.7.0_21), Tomcat(7.0.40) and TDS(Version 4.3.16 - 20130319.1353).
I have 7 day hindcast/forecasts that run once daily with output every 2 hours that I am trying to put into an fmrc. My files are named using the the start date/time of the hindcast. I want to exclude the first 24 hours of each run from "Best" datasets. I thought using offsetsGreaterEqual="26" would do the trick but it only excludes the first 24 hours from run 0 and not from subsequent runs. Meaning, if I look at hour 26 of the "Best" dataset (the first record in that dataset) I'm getting data from the beginning (first 24 hours) of run 1 instead of hour 26 from run0.
Is this the intended behavior of offsetsGreaterEqual? If so I think the documentation at: 

http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.3/reference/collections/FmrcCollection.html

should be clarified. Otherwise I'd like to report a bug.

Thanks,
David Robertson
