Also, I'm confused about the first term, 04.<162. I calculated 4<162. Did you perhaps mean 0.04<162? Here's the expression I calculated: Gs = 4<162 + (0.04<60)(5.2<63)(0.487<39)/(1-(0.487<39)(0.35<-39)) Gs = 4.834<162 Phil Eisermann H:(440) 284-3787 (mazer@ix.netcom.com) O:(440) 329-4680 (peiserma@ridgid.com)
