I was busy this weekend. Used some of the threads listed here with regards to Long term portfolio's and picked some shares from there.
After that i went to google to obtain the 10 year , 9 year, 8 year,7 year etc up to 1 year average performance of each, and then plotted them.
interesting to see how a share starts to "destabilize" once the average number of years goes less.
but still an interesting picture. Hope this helps someone else as well
