I'll disclose what I have noticed about Skaki 1.23 just in case this helps anyone determine what to do.

On a Pentium IV processor (1 cpu), Skaki will relenquish the processor to
the other engine when its turn is over.

For multicore processors, Skaki will keep one core tied up no matter what
I try.

In all cases, the debug file states that:
Ponder is on for now on
Followed by:
Ponder is off for now on

I have hyperthreading turned off with the Pentium IV. I am going to turn
hyperthreading back on and see if Skaki stays at 50% all the time.

I'm not sure that it is actually pondering, but it does locked up one of the
cores in a multicore processor, even if that core is being used for something else.

Decent list.

I will download engines based on this and determine which ones have support for Arena or Gradual Test tool.

That is great Swami, so we could know how well low ELO engines do on your STS tests.

Note that BayesElo with default settings cannot handle such a wide rating spread. The prior assumption made by BayesElo is that all engines are equally strong, and to implement that, it assigns each engine two virtual draws aginst the average opponent. For the current group, this is totaly unrealistic. It means that practically the entire rating of engines like Ram come from these two virtual draws.

You get more realistic ratings if you set prior=0.1 (in stead of the default prior=2).

The rating list does not seem so bad to me, but anyway I tried with prior=0.1 and got the exact same results. What am I doing wrong?

After ran Bayeselo, I typed the following commands:

readpgn botf.pgn
elo
mm
prior 0.1
offset 1600
ratings >rating.txt

You have to set the prior BEFORE you calculate the ratings with the mm command.
