Tarble is 10,000 but he was still a laughing-stock of the Saiyan race? a 5 digit power level was weak enough to be shipped away to a secluded peaceful planet?
I see him being like 200 at most.
He did have over 2 decades to improve, plus he was capable of causing "trouble" for Abo and Kado in some way. If taking it as a power statement, it could be assumed that his Oozaru form could be relatively close to the duo perhaps.
Either way, the 2008 OVA suggests that Roshi > Tarble at the very least. Whether we take it as Tarble being weaksauce or Roshi having made fair gains is up to debate, though with his semi-relevance against Freeza's soldiers in FnF, I'd assume the latter (especially considering how powerful Toei usually portray him as).
