e(x) fit interpretation

[IvanWilli]

Hi! great model, congrats. Simple and powerful.
I was exploring this with $\theta=80$, to focus in oldest ages. So I tried with the default example:
ages <- 0:100
years <- 1965:1990
sex <- 'female'
SWEmx <- HMD4mx$SWE[paste(ages), paste(years)]
M <- LinearLink(x = ages, mx = SWEmx, y = years, country = 'SWEDEN', theta = 80, method = 'LSE')
e80 <- 7
LT1 <- LinearLinkLT(M, ex = e80)
LT1$lt$ex[LT1$lt$x==80] #1.16

I was expecting something similar to 7 (when I play with $e_0$ prediction fits input). Am I missunderstanding something?
Thanks!
