Do the ... arms ... on the UA usually glow like that?
As an aside, I listened to the second youtube link. Sleipnir A 1. No other chittering, but interesting that it exhibited the slowest purrs yet.
As a further aside, here's a graph of binary data.
Except this ISN'T analysis of the purrs. This is generated by a program I wrote which generates a random number between 0 and 255, only counts those WITHOUT sequences of three or more consecutive bits, randomly (50/50) truncates those to 5 or 6 bits by shifting right 2 or 3 bits and then tallies them up. If you run it for 111 valid binary sequences you get the chart above.
If you run it for MANY cycles, you get distinct tiers of tally, but for shorter data samples (like we have for the UA) it repeatedly produces graphs like the above - which looks like English letter distribution, but in this case clearly isn't as it's random.
That's not to say the purrs
aren't slow-coded binary representations of characters, and I do wish that the purrs comes out to mean SOMETHING (as it's TOO binary-like), but I did a lot of analysis during the previous thread and only ever got gibberish when trying character substitution from the data that we acquired.
It is compelling when you compare the frequencies to standard letter frequencies, but that's what made me think to actually check the results of 5-and-6 bit random run-length-limited data and see what the graph looked like, and the results were a touch disappointing as they didn't just look "random" as I expected.
