[ORAS] Fastest way to max happiness?

[Black117]

Since te beginning of ORAS, I started to literally "farm" for EV berries in most of the routes. Usually I check these berries every 4-5 hours to water them just to get a max yield of 20 say hondew berries for one patch. I pitiably farmed about +1000 berries at a time period of one week so it's possible to get 999x of every ev refusing berry.
