How are points calculated? Are they something like a thousand floating point operations per point, or what?

Oh boy... this will be interesting. Explaining RAC and Credit New.

Short answer - Badly

Long answer - Using a poorly implemented, poorly specified algorithm with a poorly calibrated PID loop regulator at its core. This is seeded by a random number, which is derived from your actual run time and fudged.
This poor design and implementation means that the credit given for a "standard" work unit, on a "standard" CPU will tend, asymptotically to zero over time.

Are you kidding? Are they actually calculating it that way?
If so, this is the stupidest thing I have heard about in SETI since I found out that, due to the design of the telescope, there are two possible positions for the WOW! signal and we can't tell which one it was from.

That's a different question, a very different question, indeed it is two different questions.

If you meant in your first question "How is the location in the sky identified" then that is very simply -- it is part of the data that comes back from the telescope.

If you meant "How does SETI identify the peaks etc. in the data"? - then that's down to running a series of analysis which identify the time and relative size of peaks within the data (very, very short form of the answer)

And neither of these has any impact on the points we are awarded.

Finally, both possible sources of the "WOW!" signal have been observed on a number of occasions over the years, and have come up blank.

I certainly don't know about points...but my RAC doesn't seem to move anymore!!!

did you added some hardware or increase performance in different ways ? Else changes in RAC get smaller because it describe your recent average credits ? Which over time levels in a rather constant value.

Using Lunatics for a while but what you say actually makes sense.....I am most likely up to my daily level now...
Thank you for your response...
