Wait, I did my math wrong. Eryxc is correct once every 288 days.
A bit on the low side.
Then perhaps eryxc gains only a single minute each day, thus being correct once every four years or so.
That's closer to it.
If I want to be completely accurate, she will be right once every 3 years, 344 days, 0 hours, 20 minutes, and 41.89 seconds.
