It wouldn't have to do any of that if it was simply keeping an activity:non-activity ratio that resulted in 2 primes. I'm not sure to what degree of precision this flashing is happening but if it's very precise then there you go. 2 primes result no matter what your day/timescale/number system is.

But it's not, it's active for 90 days. You'd think they'd go for the trio.

Good one. It is rare that two primes can be added to get a third prime. And one of them is always 2. :-)

Admittedly, the options are more limited.
