SQL sys.dm_db_index_operational_stats

I am trying to understand whats going on here.

I am using the sys.dm_db_index_operational_stats on a sql server 2012 instance and I am trying to do analysis on the Singleton_lookup_count column provided by this sql function.

I understand that when all the parameters are NULL SQL looks at all the tables in the given database or I can pass DB ID and object_id for a specific table to get data for that table.

In theory that sounds great but the singleton_Lookup_counts i am getting are off by 150 Billion. That makes no sense something has to be wrong there.  

I would like to understand questions above so i can ultimately  compare Singleton_Lookup_counts between Index and Heap.

Thank you

Here is sample code

SELECT singleton_lookup_count,* FROM sys.dm_db_index_operational_stats(DB_ID(), 1542973269, NULL, NULL) 

select 
    ops.object_id         as [Object Name]
    , sum(ops.range_scan_count)         as [Range Scans]
    , sum(ops.singleton_lookup_count)   as [Singleton Lookups]
    , sum(ops.row_lock_count)           as [Row Locks]
    , sum(ops.row_lock_wait_in_ms)      as [Row Lock Waits (ms)]
    , sum(ops.page_lock_count)          as [Page Locks]
    , sum(ops.page_lock_wait_in_ms)     as [Page Lock Waits (ms)]
    , sum(ops.page_io_latch_wait_in_ms) as [Page IO Latch Wait (ms)]
from sys.dm_db_index_operational_stats(null,null,NULL,NULL) as ops
  inner join sys.indexes as idx on idx.object_id = ops.object_id and idx.index_id = ops.index_id
  inner join sys.sysindexes as sysidx on idx.object_id = sysidx.id
where ops.object_id = 1542973269 
group by ops.object_id

Select allOpen in new window

here is the data returned and difference in counts.
