A lot of members use fillers for back up and then theres some who interoperate kid Gohan SSJ2 to the one from sayain to Frieza saga.
They don't realize Gohan was 9 or 11 in the cell games arc and follow video games and say dude kid Gohan SSJ2 and got nothing on Broly 18k x100= 1,800,000
I think the Wiki is good for some information, but on a whole it's pretty ambigious and broad. You really need to know what to look for if you want information.
Wiki is definitely the worst source of info but than again IT IS a Wikipedia something that can be edited by anyone to say whatever they think should be said. Just recently I saw on YouTube some guy said Broly was the strongest movie villain barring Byrrus because the writer for the first 13 movies said so and this was on DBZ Wikipedia.
I personally dislike it, mainly due to it catering primarily for English dub info, therefore spreading large amounts of misinformation. As far as DB Info sources, I'd rely on Kanzenshuu far more.
