I am going to stop stating that PCLinux is the Gold Standard of live CD to eliminate my personnel bias on that distribution but have a Hypothetical Gold Standard defined by criteria below and with a point award of 2500.
So anything that approaches 2200 for CD version and above is potential Gold Standard and you are free to try it.
Nobody will get 100% assuming that no distribution has reached its peak and would be trying to achieve that gold wit constant improvement an bug fixes.
For DVD the point award is 3500 points and anything that tops 3000 is a good value with 90% to 95% of all software.
