1-(y/{maximum y travel}))^2*0
+2*(1-(y/{maximum y travel}))*(y/100)*{maximum deflection*2}+
y/{maximum y travel})^2*0
breaking this formula down and putting it in excel shows to me it has issues.
x = 0
y = 1
maxy = 36
maxdef = 0.1
x+ (1-(y/maxy))^2*0+2*(1-(y/maxy))*(y/100)*maxdef*2+(y/maxy)^2*0
results= 0.003888889
1-(y/maxy)^2*0 = 1
2*(1-(y/maxy))*(y/100)*maxdef*2 = 0.003888889
(y/maxy)^2*0 = 0

Found you fixed it before I could post what I found, looks like the new formula works but I thought the sag was in Z axis. This looks like a straightness issue.
