Ken,
The code below is the substitution I posted, inserted into your
original posted code. For me, it produces exactly the same value as
FastTrack, for instance, 370.531, as of 1/20/06, using my versions of
the extended proxies, slpiz and shpiz, in AB and in FT. Using slpix
and shpix, AB and FT both show 22.334 for 1/20/06.
