Is there a guide on editing legal-looking IV's? What's a Secret ID?

[Deceptional]

Hi,

I'm new to PokeSAV and I just want to edit Natures and IV's so I don't have to breed 30 eggs.

However, while researching I came upon Secret ID's, how do I consider these for the legitimacy of my Pokemon?

In addition, what is the generic rule for what IV my Pokemon can have based on it's Base stats? Obviously I'm not going to use 31's, but for my sweepers is it reasonable for a Salamence to have 28 ATK and 26 SPD? How would it's DEF and stuff compare? Like put 10 or something? How does that compare with Gyarados which has much lower base speed?

Thanks!
