Percent convergence in Iray rendering

Please forgive me as this has probably been discussed before.

What percent convergence to you typically render to using Iray? At what point does the added time spent rendering provide insufficient improvement of quality? 

Obviously this is more important to those of us doing CPU renders in Iray vs those with high end graphics cards which are Iray capable.

Thank you in advance.

    That doesn't really have an absolute answer - it would depend on where the noise was (how coincentrated it was - eyes can often be noisy due to their more complex materials and geometry, and they can represent a very small part of the render) and how obvious it was (lots of smooth surfaces and sharp details in a modernist interuior would probably make any noise more obvious than a garden scene full of gravel, dirt, and foliage).
