PFRing based on hand strength?

[Landlord79]

I see a lot of FRer's posting that they would have raised bigger with a such and such hand in order to protect it. I know this is an over-talked about subject that should have been taken care of before we came out of the basics forums, but it appears to be prevalent.

The concensus at FR is that a pfr should be 4x BB plus 1x for every limper that has acted ahead of you. A pfr should not be based on your hand strength as this will tip villains off. By making the same pfr regardless of your hand's strength, you deny your enemies critical information that they can use against you. Some vary the size of their pfr by position, but once again, this has nothing to do with their hand strength.

What are some other adjustments that are made to your pfr size that are not dependent on your hand strength?

Also, in tournament NLH, a standard reraise is 4-7x your opponents original raise. This raise size is intended to shut your opponent out by making them fold. In cash games, we're looking to make money with our big hands so we don't necessarily want to shut our opponents out preflop before any big money goes into the pot. What is a standard size for a reraise in FR cash?
