<part of the answer>....cost you $750, and at roughly about two three days render time, again on $10 an hour. I guess you could book two 800 octane bench buckets for $20 an hour and get it done half the time...
With all due respect I think your calculations/conclusions are totally missing the (main) point (or strength) or ORC:
Any render job (single still or complete set of frames) which takes over an hour you would pay the higher rate for MORE buckets...
The example above is 78.125 hours by my calculations (Renderingz, you rounded this to 75 hours)
As has been noted; animations is the real strength of ORC because you easily get over the 1 hour 'job' size.
In this example you would actually pay for 79 buckets; at a cost of $790/hour, and finishing the job in ONE HOUR...
You would never pay $790 for 79 hours (x1 bucket) and sit around waiting...
To fine tune the example;
If you had 400 frames which only take 3 minutes on a OB 250 system;
375min on Single ORC bucket (or 6.25 bucket hours)
So you buy 7 buckets for an hour; finish the job in 53.5 minutes...
Your "waste" is:
6.25Bhr req / 7.0Bhr booked = 0.89 usage * 60 (minutes bought) = 53.5mins.. ie 6.5mins your buckets of GPU's sit there idle...(10%)
FYI: waste for the original 78.125hr example is:
78.125/79=98.89% or 1.11%
I could spreadsheet this, because there would be a sweet spot for waste on every job... I assume the Otoy guys have some pre-job estimator that gives the artist instant feedback/graph so thy can work out the Time/waste ratio they are comfortable with?
If I'm correct; perhaps ORC trade mark should be: "ORC - finish any job in 1 hour"
