Why did Bellibolt's stats increase so much after EV training its SpA?

Learning about EVs

Hi guys!

I’m kinda new to this part of the game, which people call Competitive Pokemon. I’ve played only the Ruby/Sapphire and I had no idea about those IVs and EVs or Breeding and those kind of stuff.

Now I’m trying to learn about this, and I am learning EVs “training” at the moment.

So, I saw that it is better to focus on 2 stats when growing EVs, and that means that I have a maximum of 510 EVs and it should be better to do 252 in 2 of them and 4 in another. THEN I was trying to train the EVs of my Bellibolt. But when I reached 251 (62 stat points), it went directly to 256 (63 stat points). Do you know what is going on? Am I doing something wrong?

PS.: I used Power Lens for reaching close to 252, and then took away the item and increased 1 by 1 until 252.

This sounds to me like a bump stat. Likely an effect of the nature. Natures raise the actual stat by 10% (rounded down) which means if you were to have 99 in a stat you’d get 9 extra points on top of that from your nature. Then, after increasing the stat by one point to 100 you’ll then get a 10th extra point meaning you got 2 stat points for the price of one.

I also just plugged your EV training into Pokemon showdown on a Bellibolt and that is exactly what happened. At least you’re keeping track of your EVs correctly!
