Alan,

I see you sent the message to Robb, so I'll let him answer 
more competely, but here is a quick impression:

The easiest thing to do is probably let the 15 minute precip mode file
just overwrite the 10 minute file.  In other words, you are matching 
both 10 and 15 with the (1[0-9]) pattern at the end, but you can
write them to the same file name instead of using the \6 pattern.
This would be OK, unless you absolutely want the filename to be the
exact time of the data.

For example:
WSI     
^NEX/(...)/BREF1/..([0-9][0-9])([0-1][0-9])([0-3][0-9])([0-2][0-9])(1[0-9])
        FILE    -overwrite      data/nexrad/\2/\1r0/\3\4\510.nid


This way, any image from 10-19 minutes would be written to a file name
using 10 as the minutes. A subsequent image would overwrite the previous
using the -overwrite tage to FILE. Without -overwrite, the data
would be appended.
