Here's the result (which agrees with what you've mentioned):

I first ran 3000 frames of animation (3000 total spheres at the end), with
Bounding OFF. Render time for the 3000-th frame: 102.16 seconds

Then ran 2-frame animation as you indicated, with Bounding OFF as well. Render
time for 2nd frame: 102.31 seconds.

That's pretty close!!

(I cheated a bit on the set-up--which didn't alter the results--to save some
tedium: For the 3000-frame animation, I just set Bounding_Threshold to
3003--effectively off. Then ran only frame 3000.)

BTW, as a reference to these render times: When Bounding is ON and working,
those 3000 spheres take just .5 sec to render! About 200X faster. Hmm...Bounding
is a GOOD thing.  ;-)
