Well, that depends. If all your data can be expected to fit in memory
then it is a realistic value. (If not, you should be real careful not
to make performance decisions on the basis of test cases that *do* fit
in RAM...)
In any case, if I recall your numbers correctly you shouldn't need to
drop it nearly that far to get the thing to make the right choice.
A lot of people run with random_page_cost set to 2 or so.
