In practice, if the file is large, scrollbar operations are less 
accurate and less smooth anyway, so you can get away with rough 
estimations very well without further compromising the scroll quality.

However the smaller the file the better a scrollbar can work and that 
is why accurate size calculations are especially beneficial for small 
files rsp. well choosen small parts of a file, such as at the top and 
the bottom.
