I've not used focal blur much. What settings would be a good starting point?

My personal recipe:
Confidence .9
Variance 1/64
Samples to taste, for quicker renders, 10 does the job. For final
renders I'll go as high as 1000.
Why 1/64 on variance? Well, pixel-to-pixel it's very hard to see the
difference between a value that's 4 levels different than the next
(Though 3.7's gamma may change that in shadow or highlight areas) If you
must, go for the default variance. It slows a little bit, but not much.
As for confidence? Dunno. .9 is just sort of an arbitrary value.
Either than or start with the defaults, They're good enough (except
samples) occasionally I'll push confidence to 3 nines or even 4 nines,
if I think I'm going to get anything out of it.

Thanks I'm running a render on my old dual core laptop. with the default
values and samples 10 and aperture 0.400.
It is rendering at 8 pps 2 hours into it an 17% done.
I'll try variance = 1/64 next.

I sympathise my wife has that problem. I on the other hand sleep the
sleep of the just.
I would have thought that long nights and short days would meen that you
sleep longer.

Jim, she's ~929 units tall; try this with my version of the mesh to make her ~5
units tall:
camera {
location <0, 0, -15>
look_at <0, 0, 0>
right x*image_width/image_height
angle 60
}
light_source{ <-300, 300, -300> rgb 1 }
#include "shapes.inc"
#include "Lucy_POV_geom.inc"
#declare Lucy_Statue = object {
Center_Object(Lucy_Statue, x+y+z)
scale 1/929*5
rotate y*180
}
object { Lucy_Statue pigment { rgb 1 } }
Cheers,
Rob

Ok ... here's my version rendered with RC4. I've settled for a more
subtle effect
