Based on everything I have looked at (analysis of positions etc), PF 2 is more
akin to Shredder 7 and not Shredder 7.04.   On a Dell Axim running at 400 Mhz,
it appears to be about 12=15x slower than a P4 1.7 Ghz which runs pretty close
to a P3 1.2Ghz.

If one assumes for the moment that doubling of speed is worth 50 points (which
is high IMO - I think it's closer to 35-40 points at the high end) - then we can
work backwards.  For simplicity. let's just say an Axim is 16X slower than 1,2
Ghz (it's not - but this make the numbers easier to work with).

16x = 2^4.  So we take 50 x 4= 200 points - so in the case PF2 on a Dell Axim
running Mobile 2003 is equal to 2570 to SSDF conservatively.  This over 200
points higher than any estimate for any program running on the Palm Tungsten and
clearly ahead of any dedidicated unit..  This clearly in IM range and maybe even
weak GM level.  A 206 Mhz ARM would be about 100 points less than this or 2400
SSDF under this scenario.  IMO, it is only about 70 points less.
