Is there a rule of thumb for using Rushmore as
opposed to Explicit indexes, i.e.

SELECT Customer
SET ORDER TO 0
LOCATE FOR CustId = "12345"

       vs.

SEEK "12345" ;
   IN Customer ;
   ORDER CustId

Both should yeild the same result (barring any
fat finger errors on my part in the example
above). VFP should encounter a little bit of
overhead in determining which index to use
(i.e. it's "strategy") but is there a minimum
number of records that must be in the table to
make Rushmore worth while? Is there a minimum
number of optimizable expressions? That kinda
thing.

TIA for any feedback you guys can give me.
