You don't specify a choice algorithm? Might want to change your script with a quick thing like this to view all the candidates. I use a similar 120day and I've looked at atime/ctimes of them before and was happy with the output. You can then quickly size the output with a quick sed/awk/whatever.
SHOW (varchar(file_size) || ' ' || varchar(USER_ID)) WHERE DAYS(CURRENT_TIMESTAMP) - DAYS(ACCESS_TIME) >= 180 and add "--choice-algorithm exact" to the command line to see what files match. I can't recall what the default is. Might already be exact? Oops, man pages says yes. Might then run all 3 and see if the output is much different.
