Revisioning..... ???

Hello all, and thanks in advance for any assistance you can provide

I have a number of questions related to revisioning.....

  1. When using a "Revision Table" in a drawing where does the property for the next revision value live?
  2. Does using PDM workgroup adjust or update the next value or sequencing information when drawings are checked in?
  3. Does the "Revision Table" have the ability to be set to a different sequencing  ie.( 1.a; 1.b;1.c ... etc) or is it hard coded to be (A;B:C...) always?
  4. Why is such an important part of everyday workflow for most users such a disaster and poorly documented part of the software?

Thanks for your input
