Campy RD limit screws vs. Shimano's ??

Limit screws may be real basic stuff, but I want to be sure since in the near future I'll be installing my first Campy RD (Centaur 11) after years of installing lots of Shimano RDs.

Now if you don't know, the instructions for every Shimano RD I've seen have you adjust the low limit screw so that the jockey pulley is directly beneath the biggest cog. But the high limit screw should be adjusted so that the jockey pulley is just to the outside of the smallest cog. Kinda like the left side of the pulley virtually touches the right side of the smallest cog when viewed from the rear. I've always done it that way, even when using Jtek Shiftmates, and it works well.

So what about Campagnolo? I'm guessing Campy's RD limit screws need to place the jockey pulley directly beneath both largest and smallest cogs. Is that correct? Do the two brands of rear mechs differ in that way?

Or something else?

Thanks for your perspective.
