The Table_Check is when to check for an update to the table, while Table_Reload reloads the whole table.
If they are the same value, then it will not do a check, but always just reload the table. So to just have the table check 1 time a week and not reload at all, set TABLE_RELOAD to "-1" (Setting to -1 disable the option) and leave Table_check set to the Week value.
