"The conversion ratios John has reported for 4 pro

The formula is: mass in = mass out.
Anyone can get those same conversions. Dynamotive published how their oil yield varied with temperature, about a decade ago. The oil yield was very high, around 90%, for real garbage. I'm guessing they could do even better with hydrocarbon-only plastics like PTOI is using...and no heat transfer fluid required either. No, Dynamotive couldn't make a profit either.
For PTOI, if you do the math you'll see that the cost of the sorted plastics needed by PTOI, which are HDPE, PP and LDPE, is around $800/ton. In weight terms, pure diesel doesn't cost that much more. Remember, mass in = mass out.
Do the math. You'll see that not only was Mr. Bordynuik lying about $10/bbl oil cost with a sales price of WTI-$3, but that any profit at all is impossible.
