You will also have to deal with the vertical scroll thumb will not go all the way to the top or be sized relative to the number of rows. Parameterized views do not suffer these problems.

are you saying that if i am outputting a report from a table
with (say) 358 thousand records, that performance will be better if i
base the report on a parameterized view of that table as opposed to setting
a filter on the table and using the table itself ?
