Radar's solution (and the subsequent variations) should work regardless what the number is... does it not? If not, what happens?

xbssnapshot
XBSSNAPSHOT(1) CoreXBS Tools XBSSNAPSHOT(1)
NAME
xbssnapshot - CoreXBS snapshot utility
SYNOPSIS
xbssnapshot fetch [--[no]live] [--age hours] [--[no]xpc] train_name
xbssnapshot authcheck [--timeout seconds] train_name
DESCRIPTION
In the 1st form, xbssnapshot is used to obtain a snapshot of Cortex for train_name. A cache of snapshots is maintained in a directory,
which may or may not be used in addition to consulting the Cortex servers depending on command line OPTIONS specified. If successful, a
file URL of a suitable snasphot is printed to STDOUT. On failure, a description of the failure is printed to STDERR.
In the 2nd form, xbssnapshot is used to check connectivity to the Cortex servers for train_name and determine if AppleConnect (Single
Sign-On) credentials will be required to obtain a snapshot. If the Cortex server can be reached, YES is printed to STDOUT if SSO authenti-
cation is required and NO is printed if not. On failure (including not being able to reach the Cortex servers), a description of the fail-
ure is printed to STDERR.
OPTIONS
--live Force xbssnapshot to bypass the snapshot cache directory and fetch data from Cortex.
--nolive
Force xbssnapshot to not fetch data from Cortex and only use the snapshot cache directory.
--age hours
When considering if a snapshot found in the snapshot cache directory is "new enough", only accept snapshots that are less than hours
old.
--xpc Use XPC service when fetching data from Cortex. This is the default.
--noxpc
Bypass XPC service when fetching data from Cortex.
--timeout seconds
When performing connectivity test with Cortex server(s), how long to wait before assuming no connectivity to a given Cortex server.
RETURN VALUES
Returns 0 on success, and non-zero on failure.
ENVIRONMENT
CTXHost
May be set to the hostname of a specific Cortex server. This is mainly only useful to the developers.
CTXPort
May be set to specific port to connect to CTXHost on (does nothing unless CTXHost is also set). This is mainly only useful to the
developers.
FILES
/Library/Caches/com.apple.bni.cortexsnapshot
Directory where snapshots are cached.
/var/log/system.log
CoreXBS framework and XPC services log here. grep CoreXBS /var/log/system.log may show additional information above and beyond what
xbssnapshot prints on it's own.
BUGS
