Does Yael have variance?

[bktroost]

I already have the exact spawn time. I have spawn times for every important mob...that information is less private than people think and far easier to get than people realize. This game isn't new, anyone who really cares about that can get it. Secrets are hardly secrets in EQ.

I have a guess at his variance table, but I was wondering if anyone, for the sake of academics, actually kept logs and compiled the information. Watching his spawn times from past logs and seeing what the maximum variance has been. My logs dump previous spawn windows unfortunately, so I don't have this data.
