Black 2 Hidden Grottos?

Question

Okay I have several questions about the Hidden Grottos in Black 2
1.When does the game start counting the steps for the Hidden Grotto to regenerate?
2. What's the best way to 'Farm' the Hidden Grottos?
3. is the Gender ratio of Pokemon that can be found in the Hidden Grotto different when they are IN the hidden grotto?

If you can answer any of these, thanks

Answer 1

1. Either the moment you begin your game or when Bianca introduces Hidden Grottos to you.

2. I guess the best way is to train on a route that has a HG with the Pokemon you want, and check every 5 minutes or so. That or just continue your game normally and go around the HGs once in a while. To be honest, if you check every single HG one after another, by the time you've visited the last one you'll have gone 256 steps.

3. I don't know exactly what you mean by this?

For the third bit I mean if a Pokemon has a 50/50 gender ratio outside a hidden grotto, is it the same inside the hidden grotto? because I've been SRing for a Female Murkrow and all I can get are Males...

No, it's not the same. Serebii lists the percentage for male/ female Pokemon in Hidden Grottos: http://www.serebii.net/black2white2/hiddengrotto.shtml
