Lattez Episode
Goku: 416
Piccolo: 403
Vegeta: 18,000 (a year in the spaceship)
Vegeta Comes to Town Episode
Goku: 5,000 (as measured by the Fighting Strength Tester, actually the norm should be more than 5,000, I'm guessing it's 1W) Jaikai Fist is not to be confused. Go multiply it yourself (doubling the KAI King Fist is a 50% increase)
Piccolo: 1200
Vegeta: 18,000 (seems to be almost 2W) Giant Ape-ization: 7W (Giant Ape should be 10 times the norm, because Goku and Vegeta had a heated battle before, so Vegeta's stamina dropped a lot, and his fighting power dropped as well)
The Frieza Episode
Goku: 300W (a lot of boosting steps were omitted in the middle, anyway, after gravity training and medical recovery from serious injuries to reach this value) Super Saiyan form: 150,000,000,000W (50 times the norm)
Beaker: more than 1,000,000,000 (and Neru merged, it would have been only a few tens of thousands, assimilating it is really amazingly powerful!)
Vegeta: estimated to be only 100,000,000, at most 20W (and Guise won the battle, and Piccolo later said: Vegeta I still have a way (can beat him), Frieza will not be able to, from this point of view it should not be more than 20W)
Bioroids Chapter
Goku: 400 million (Super Saiyan form)
Piccolo: only a few tens of millions, should be Less than 100 million, doesn't seem to raise much
Vegeta: 400+ million (Super Saiyan form, easily beat 19, but not in seconds, should be less than 500 million)
