>I have a large table that I need to count the number of records on a regular basis. I was using - Count to nRecords - but it got to be too slow. So I created an index on Deleted() and am now using the following code. It is now instant.

If you want the number of undeleted records you could also take the difference of RECCOUNT() - nDel. No big deal since this only saves you 1 line of code.
