Problem is, it is impossible to determine randomness based on such a small sample. Humans very good at spotting patterns, which we can almost certainly find where there are none.
(Besides, the chance of getting CDCBAECDAEDCBAEDCC is just as big as getting AAAAAAAAAAAAAAAAAA or ABCDEABCDEABCDEABC.).
Here's a random 18-character A-E string based on data from random.org (so supposedly truly random):.
DADEDACBABACBACCCE.
Does that look random to you? To me, definitely not.
Anyway, as Prof. Grumbles already noted, the past two hours, the oldpix did.
change again; so Time is not standing still (yet). The sequence is now: CDCBAECDAEDCBAEDCCDC.
