It seemed to scream down through the sky area in under 3 minutes, and when
it hit the grass, it went down to about 30pps



I used these rad settings.

global_settings {
 assumed_gamma 0.8
 ambient_light rgb .5

    radiosity {
      pretrace_start 0.08
      pretrace_end   0.01

Cool. I want to know how to get the total time less than the time for 
trace on *my* pictures! :-)  Methinks there's some seconds->readable 
flaws in there, or some hand editting.

And note the strangeness of the Hour/Minute/Second system, whereby 13898 
is actually less than 13811 ;-)  This is worse than the Yard/Foot/Inch 
system, or Pounds/Shillings/Whatever (not being British, I never figured 
that one out.)

i think this happens on the linux version if you use the "Close image on
click" switch (what is it, +P?) and don't click the image for a while after
it is done rendering. i see it happen when i let a render go overnight. then
it's a matter of hours difference between the two.

Nope, no hand editing, BUT there's a problem with the gamma on my wife's
monitor, so when I brighten them up for posting,  I'm washing them out
somewhat.
it looks about 5% darker on her screen than it does here.
 oh yeah I traced it a lot larger than this and sized it down for posting.

Hmmm that is odd.  Of all the tings computers do well, counting should be a
cake-walk...
FYI this was on a WINXP system.  Maybe it's like bytes where 13898 bytes =
13.57K
:D

well it seems to continue counting after the trace has ended. so if it was
an hour long trace, then the image remained "up" for 2 hours until i clicked
on it to close it, the Time For Trace would have been 1 hour, and the Total
Time would have been 3 hours. Maybe i have this backwards... i forget. and
maybe this is completely unrelated to your problem :)
