- You had the original FUNimation dub with The Ocean Group (Saffron Henderson playing both) = Goku +1, Gohan +1
- You had the dub of DB movie 2 prior to "Season 3" of DBZ with Nadolny* as Goku = Goku +2, Gohan +1
- You had the dub of DB movie 3 in 2001 with Delgadillo = Goku +3, Gohan +1
- You had "Season 3" onwards with Nadolny as Gohan = Goku +3, Gohan +2
- You had the re- and continued-dub of the DB TV series (as well as DB movie 4) keeping Nadolny = Goku +3 or +4 (depending on your counting methods; it technically "replaced" Delgadillo), Gohan +2
- You had the dub of DBGT with Nadolny as Goku = (how do you want to count this? probably not by adding anything...) = Goku +3 or +4 (depending on your counting methods), Gohan +2
- You have the new dub of Kai with Clinkenbeard = Goku +3 or +4 (depending on your counting methods, even more if you consider she appears to have handled the baby Goku stuff), Gohan +3
You certainly have a point with regard to the amount of time spent with each voice (an "entire" two series, though even in both DB and DBGT Schemmel takes over for the "adult" Goku roles in the last tournament and SSJ4 / other "adult" appearances).
Also, forget about the release date of Origins 2... I'm fairly certain that the dialogue was recorded far in advance (if not sampled from somewhere else), so the final cast of Kai may not have been decided or settled upon, or been fully put into use yet... the times just don't correlate, so we really can't and shouldn't use that as evidence for anything.
For the record, does anyone else hear Clinkenbeard in Goku's "Ka - me - ha - me - HA!" and Nadolny in all other bits of dialogue in that game...? I'm not convinced it's all the same voice through and through.
