Abnormal Stats Flygon?

Yes, it's time for another one of my overstat Pokemon! Every now and then, in one of my Pokemon games, I get extremely lucky, and I have abnormally high stat's on one Pokemon, or IV's!

Previously, on a different forum, I shared with people my AMAZING Solrock.
No glitches, no action replay, just plain and caught in Pokemon XD GOD! Now, here's the shock about it, the solrock gained 5-7 stats in attack EVERY level up, no EV training!
The amazing Solrock alone had higher attack than an Adamant Groudon!


And yes, it did learn Explosion. xP


Well, now I've come to realize I have not an over stat Flygon, but rather over spread out stats.

It's stats are:
Nature: Adamant
Hp: 337
Attack: 313
Defense: 247
Sp.Attack: 175
Sp.Def: 231
Speed: 279

So now I ask you, the people, is this overly high for a Flygon or perfectly normal?

But... how do you expect people to tell if it's "over-stat" when you don't even post the IV and EV?


[Edit]
I opened up a calculation tool on Pokedex.jp, and did some calculating... I'm assuming all the IV's are 31 (which is highly unlikely.)
Thus, some values maybe be 'off'.
IV/EV
HP: 31/144
ATT: 31/196
DEF: 31/?
S.AT: 31/?
S.DF: 31/?
AGI: 31?

OK.

Something definitely is wrong here.
Even assuming that your Flygon has all 31's, it's impossible for it to get 247 defense, since according to your stats and nature, your Flygon needs 340 EV's to reach 337 HP and 313 AT, thus only leaving 170 EV left to use.

And even when putting 170 EV's into DEF, it's impossible for a Flygon to get 247 DEF (you get 238 with 31 DEF IV) in your case.

Thus, I assume it's a bug of some sort, or you used some sort of cheating/hacking device.
