EDIT: Read my post below.
Now that the topic at hand has been settled, I'd like to briefly discuss something, although, I'm not quite fond of being crucified, so please be patient with me and no snarkiness, as this is a genuine question.
Why is Saiyan Saga Vegeta Planet-Level? Statements made by oneself in shounen manga are usually not that reliable, if they weren't, Boros would have been accepted as Planet-Level long ago.
So let's look at power-levels. We know that power-levels were only legit up to Namek Saga. Here's a list of the official power-levels:
http://dragonball.wikia.com/wiki/List_of_power_levels
Raditz' power-level is 1200. SS Vegeta's power-level is 24000 when using Galick Gun by virtue of matching Kaioken x3 Goku. 24000/1200 = 20
Raditz is generally accepted as Moon-Level. Here, he is listed as Moon-Level+ with a calc, but that calc is outdated by nearly 4 years and the pages it links to, which are the basis of the calc, are invalid except for one that talks about the mass of the moon and a projectile motion calculator.
As per the attack potency chart here, if you're low-end Moon-Level, you need to be 4000 times stronger in order to be low-end Planet-Level, but since the attack potency chart is being redone, I'll use the values provided by the OBD wiki.
http://outskirtsbattledomewiki.com/index.php/wiki-rules/13-general-obd-terms/80-destructive-capacity
Moon-Level = 29 exatons.
Planet-level = 57.3 zettatons.
57.3/0.029 = 1976
So you need to destroy our moon 1976 over in order to be Planet-Level.
So in order for SS Vegeta to be Planet-Level, Raditz would have to be Small Planet-Level.
So there's two paths here.
Either someone does a calc for Piccolo's Beam that would put Raditz at Small Planet-Level, OR, we have something to go by that would make Vegeta's statement legit.
