Should I be using a 30 second observation freq. for Opus RS?

From the OPUS website :

"Provide OPUS a GPS observables data file in any format (for automatic conversion to RINEX format by UNAVCO's teqc converter) or convert it to RINEX yourself first. OPUS also recognizes compressed (UNIX or Hatanaka.yyd) or zipped (gzip or pkzip) files, including multiple data files in a single zip archive.
OPUS accepts receiver epoch rates of 1,2,3,5,10,15 or 30 seconds, all of which are decimated to 30 seconds for processing. Note: Though your data file may already contain survey metadata, including antenna type, height, and mark information; these are IGNORED as we have found they are inconsistenly formatted"

I know this applies to regular OPUS, but I couldn't find if this is specific to OPUS-RS.

Thanks.
