Visualization preferences: what are you typical sag when you work in CATIA?

Hi gang

We currently have some discussions on default preferences (or settings) you people are using when doing your daily work in 3D. Whether you are in V5 or 3DEXPERIENCE? what are the typical value you prefer to set for 2D and 3D accuracy? Do you use fix or proportional? a large sag (like 50.2mm) or a small one (something like 0.02mm for instance) ?
