I think the original structure and definition of the variables was ok. That is, the odd 1a2a entry of 71.25% was a direct result of the 15% gammon rate entered for the trailer.

Working with the original Zadeh program and definition of G1 I was able to create a credible looking MET just by altering "gammon-rate-trailer" to a more sensible figure in the 25%-28% range.

Is Zadeh's original article avaialable online anywhere? I've been unable to access it with a Google search.

I re-read ZAdeh's article, and he doesn't mention which parameter to use for the pre-Crawford 1-away values, but the only way I could reproduce his table was by using G1 for the trailer.

From Nardy's site:

Sun Mar 28
use G1 for calculation of 1-away pre-Crawford values (matchequity.c)

I think this should be calculated from the trailers gammon rate and G1 appears to be gammon-rate-leader in Zadeh's tabe, i.e.

<pre-crawford-table type="zadeh">

<parameters>
<parameter name="gammon-rate-leader">0.25</parameter>
<parameter name="gammon-rate-trailer">0.15</parameter>
<parameter name="delta">0.08</parameter>
<parameter name="delta-bar">0.06</parameter>
</parameters>

</pre-crawford-table>

As an aside, are there any other MET generating programs available that will allow me to experiment? I was wondering if Mec26 was available in a format suitable for this. I'm doing a project that involves Gnubg rollouts and theoretical MET generation. Playing with some source code (or at least the parameters for the code) would be very useful to me.

Thanks, Ian.
