Actually with my shuffle I'm fine, the only point I started to be concerned "how many shuffles do I have to do to have a random order compared to the one from the start?"

Something like this (forgive me for the video, but it is interesting, check at least the first 45 seconds, there are also links to papers in the description)

If you use Joe Horn's code to shuffle the list, a single shuffle is completely random. A new shuffle would give you a new ordering. What his code does is place the any element into slot 1, then any remaining element into slot 2, etc.
