This was actually when they were six. And they had to run that mile many, many times.
As Caboose showed, Spartan-IIIs were trained to be better. Their training was unique and more effective than the Spartan-IVs because it was tougher. The Spartan-IIIs were ready for anything and didn't have anywhere near as many emotions as Spartan-IVs would. You say it doesn't prove anything, but maybe it would if you actually check Alpha, Beta, and Gamma Company's augmentations, especially Gamma Company's. They are better overall than Spartan-IVs in pretty much every factor.
I see your point about the augmentations for intelligence with the Spartan-IIs, and you are correct, but they were stilled trained very well mentally as well as physically. Most of their intelligence was taught to them, not augmented into their brains. The Chief could calculate easily because of his Helmet's Visor and he was trained with this part of Physics.
No, the numbers did not at all bother me, I was just saying so.
About only Noble Team having MJOLNIR Mark-V armour, I'm confident that you're wrong about that. Last time I read, all Spartan-IIIs were issued MJLONIR Mark-IV Armour during the Fall of Reach to support the war effort. Although SPI Armour can be useful because of it's camouflage ability, it's still detectable and not as good when you are found by your enemy. If I were to put Fireteam Majestic in Halo 4 against Noble Team in Halo: Reach, who do you think will win? (Take away any Member of Noble Team to balance the number) I'm sure that even if you take away Noble 6, Noble team will still win.
Well you still haven't thrown a point back at me as to why the ODST's training is on par with the Spartan-IIs. You can still prove me wrong because I think that the Spartan-IIs have more intense, rougher, and tougher training. I gave my evidence about that on the last page, now give me yours if you would like to continue.
Note: I'm not trying to sound aggressive or anything, I'm just countering anything I disagree with.
