This should definitely be faster. I've tested it for ASC sort but not for DESC -- I believe I've coded it to correctly handle DESC sort, I just haven't...

As an aside, if possible, TRUNCATE the table rather than use DELETE to reduce logging.

Code below could perform better, esp. if table2 and table3 don't have an index that directly supports the lookup/comparison being done.
Edit: And performance could be worse with this code ......

Another perfect situation for a tally table. You can create an in-line table using CROSS JOINs or create a physical tally table and use that. Unfortunately I can't...

If the code ran in just 8 minutes, and you like it and results, it's logical for you to leave it as is.

I agree. You'd expect the specifically-chosen (?) "featured script" to be something at least moderately good/useful, but most often they are not.
As for this code, I would suggest simply:

There could also be some type of locking, and thus blocking, on the underlying system tables. I've seen this happen when, for example, people do a "SELECT ... INTO...

Since you're trying to do a keyed lookup on the CL table, the conversion should be other way around to allow SQL to do a seek on all three key...

I see a couple of other issues, besides formatting, with your code.
1) Step 0 is a summary for the entire job, including duration. So if you add step 0...

there is a pre-set default fillfactor, but I've seen it set as low as 70%, it's not automatically 100%.

...Be careful of fillfactor, else it is possible that your table ends up taking up more space, unless that is what is expected.
If your choice of a clustered index...
