User blog comment:Imperial Wyrm/My power levels for Bardock: Father of Goku and History of Trunks/@comment-5745743-20160628033815/@comment-5718774-20160628034950

Bardock's power level was stated to be CLOSE to 10,000 not explicitly 10,000. Also, Future Gohan is stated to be as strong as Frieza Saga Goku and Future Teen Trunks is way weaker than him. I'd say he'd be able to defeat third form Frieza but not fourth form.
