Question for Pokemon Black 2

Okay, so I found a Timburr in Pinwheel Forest, who's original trainer was N; and I don't know why. But I talked to the Stats Judge in Nimbasa City, and he said that his potential was outstanding overall, and so I decided to manually train him to level 100 on Route 18 with the Audino's. I trained him to level 85, and at this point he had already evolved into Gurdurr, and I saved, then used my only 15 rare candies to get him to level 100, so I could record his stats and use the Serebii IV Calculator.

I input the stats, along with the nature, which is Rash, and here are the stats:

HP: 346
Attack: 253
Defense: 209
Sp. Atk: 127
Sp. Def: 122
Speed: 116

And it's ability is Guts.

When I input it into the Serebii Calculator, it says that one of the stats is not correct; the Defense is said to be from 175 to 206, but my Defense is 209, so it doesn't compute. When I turn down the Defense to 206, then it moves on to Attack, where it should be from 215 to 246, and mine is at 253. When I turn that down to 246, HP's top stat is said to be at 311 top, but mine is at 346. And it stops there, and it says I have perfect IV's. I put the EP points at 0 (since I don't know whether I did EV train them or not, I just leveled him up) so I want to make sure that this is accurate.

I did not hack my game; I'm keeping it hack-free, and I just want to make sure I am accurate in my IV's.

Thank you!
