[FIXED] Is it a bug in the file "[Joomla1.5]\installation\sql\sample_data.sql" ? - Joomla! Forum - community, help and support

my joomla :

version:1.5beta

os:win xp

db:mysql server

questions:  think should be: sum(#_poll_data.hits) == count(#_poll_date) == #_polls.voters

                sample_data.sql tell :  sum(#_poll_data.hits) = 8 , 8 hits
                                                              count(#_poll_date) = 7 , 7 records
                                                              #_polls.voters = 8 , 8 voters.

open file "[joomla1.5]\installation\sql\sample_data.sql"  , find lines tables "#_poll_data,#_poll_date,#_polls," , below follow:

insert `#__poll_data` values (1, 14, 'community sites', 2);
insert `#__poll_data` values (2, 14, 'public brand sites', 2);
