Goku VS Superman Statistics

Before I start, I'd just like to say I don't want to spark any debate, hate, or controversy off of this. I'm only sharing the math that I managed to calculate. As a die-hard DBZ (and Superman) fan, I had a feeling that the stats were off for Goku. So without further ado, here's my own research. I did this after hours and hours of doing some long Math, and I even had to miss a few assignments. But hey, in my opinion it was worth it!
BEFORE YOU CONTINUE, READ THIS. HERE ARE SOME THINGS THAT SCREWATTACK WERE WRONG ABOUT/FAILED AT:

• Screw Attack tried to make power levels completely useless, however they didn't provide the PROPER reasons. HERE are the reasons: Ki can be suppressed, so if they are inaccurate, the power level is weaker than the warrior actually is. Second, they became irrelevant to the story. What would be the point of them if they only made warriors look weaker than they are?
• THEY USED GT. GT WAS COMPLETELY NON-CANON. It shouldn't have even been in the fight in the first place! So, for this re-analysis, we will not be using any statistics or factors from GT.
• ALSO, they judged strength only on how much Superman and Goku would lift, when rather it should be judged on how much force said warrior can exert by themselves. This applies to Goku moreso than Superman, since he can exert Ki which amplifies his physical bodies' capabilities (SIGNIFICANTLY), as well as transfer it in an out-of-body way. For example, the strength of Goku's Kamehameha should be inputted into the actual battle. Screw Attack greatly overlooked this; only keeping in mind a traditional definition of strength.
• Finally, when using the part in DBZ where Goku was struggling to lift the weights, this wasn't his true power. Goku was using absolutely no ki when he was doing this. Goku has the ability to reduce his power to normal HUMAN levels if he so chooses. One example is how Goku was hurt when Krillin threw a rock at his face. Another example is how Goku is afraid of needles! When he is in medical care after the Saiyan saga and is about to be injected with a needle, he freaks out. Why? Because he's FORCED to be in normal human conditions. He's obviously not going to power up! It would cause the room to blow up and the needle would blend on his skin! Anyways, back to my point. In the manga, you obviously see NO aura around Goku, which leads us to assume that he was completely powered down and didn't expect the weights to weigh as much as they did! Toriyama makes him go Super Saiyan so King Kai could demonstrate how drastic Super Saiyan 1 is. If Goku used even a LITTLE Ki in base form, he would be able to easily the weights, too. And if anyone says "you shouldn't assume", Toriyama wants us to assume. Here's the scan:
