As for Abo Cado. There's no way to tell and I would think he probably did mean more towards the stronger sides of Freeza. He did make mention at measuring his PL in his transformed appearances so they were probably on record or people got a readin afterwords. I still lean more towards them each being like 50% Freeza. For Goten and Trunks though, I don't think they get the same boon for going SSJ as Goku and Vegeta do, if only because they are still Kids and their bodies aren't developed enough to allow them to actually full make use of the transformation.
Kinda like how Goku as a Kid, though having learned the Kamehameha and was as strong as Roshi, didn't have the same kind of destructive power Roshi had until he got older and more developed. Which would also explain #18 commenting on Goten's lack of energy control.
