RUC sounding info

Hi there, I have two questions.

I am using RUC 20km profiles from which I need most unstable CAPE, CIN and some other parameters. For dates from 2008-2010 I get the data from the NOMADS http server, for dates from 2006-2007 I have to order it. From all these data sets, it seems the record number for CAPE keeps changing. I don't download the inventory files, but I can see them on the http server. Sometimes the best/MUCAPE is in record number 311 and for other dates it's in 309. Is there any way I can know which dates have which record number, or should I use the .inv file with each grib file? I saw that precipitable water before 2009 is in number 297 and after 2009 it's in 295, but I can't make the same conclusion for the best/MUCAPE and CIN.

Also, can you please tell me whether the CAPE and CIN are computed using virtual temperature or not?

Thank you
Danelle
