may be related to the number of rows in the table ?when rows is small,it will not affect,but ,when rows is much ,it will affect.

run this first:
=========
DBCC SHOWCONTIG (table_name,index_name)
GO
=========

note the fragmentation and scan density.....

The execute;
==============
DBCC DBREINDEX('table_name',index_name,54)
==============

see any difference in logical frag and extent scan frag?
is your scan density = 100% ?
is your "Avg Pages per extend = 8" ?
