5th Gen EV training questions

[Seanwashere]

I have some questions about EV training.

I wanna make sure I'm doing this correctly so here goes:
This is what I did:
I hatched a sneasel and gave it 20 vitamins. 10 proteins and 10 carbos(attack and speed).
So all I need is to get 152 more EV's right?
After that, I equipped my sneasel with a power bracer and killed 30 patrat and unequipped the power bracer and killed 2 patrats. Since power items give +4, patrat give +1 attack. So 5x30=150 and +2 = 152.
And
If i kill 25 basculin with power anklet equipped to my sneasel it will equal to 150 then i kill 2 without power anklet equipped it will give me 152 right? (basulin gives +2 speed).
and the leftover 4 EVs i kill 2 audino for it and im done?
Questions
1. Is this right?
2. After I get all my EVs in the desired stat can i power level like use rare candies/feed it wonder brunches(the deli person in join avenue) to make it lv100? And will it affect my stats?(I saw on a forum site and it said after you get all the EV's for the stats you want you can fight any pokemon or power level and it won't affect your stats.) I wanna make sure if that person is correct?

Please reply back!

Note: This is for gen 5/black 2 NOT x/y so don't say anything about super training...

Can someone reply....like seriously?

Both questions are right, except one minor detail. You only need to get one more Basculin without the Power item, not two. Because Basculins give +2 EVs on Speed. And fighting two will give you 4. The limit for each stat is 255, but 3 extra EVs are a waste so 252 is the ideal number. That extra Basculin made your Speed total 254, so getting the Audinos was pointless since the EVs they yielded would amount to nothing. Other than that it's good.

Thxs WhiteknightL for your reply. Seems like the calculator was right. After 2 weeks of posting this question I finally got a nice reply.

This may be about 5th gen, but please keep in mind for next time that we have a competitive battling section that has guides to help with these questions, and they even have a Quick Questions thread like we do here.
The Battle Center is where you can get more results.

And a word of advice, don't rush people to reply to your thread, that only makes them want to post in it less.

Closed due to being in wrong section.
