I changed the formula on the IF-CNRGATH curve in the EastMrkt file.
Before  the change it was CGT/APPALAC - $.32.
After the change its (CGAS -  $.30)x(1-.0492).
This widens the spread by about $.24.

I changed the formula on the IF-CNRGATH curve in the EastMrkt file.
Before the change it was CGT/APPALAC - <CUR><NUMBER>.
After the change its (CGAS - <CUR><NUMBER>)x(<NUMBER>-<NUMBER>).
This widens the spread by about <CUR><NUMBER>.
