Obviously you wouldn't in this case. But imagine a Customer Service
application. You show the user the customer's orders in descending date
sequence. Chances are the user is interested in a fairly recent order,
which should be early in the subfile. If you've built a 9999 record
subfile of all the orders the customer has placed since 1996, then
you've wasted resources, user time, electricity etc...

I do not follow this. If the desired data is in the 300th record, how
does one get there on the first or second subfile page?
