Wouldn't it be great if we had Exxon's or Chevron'

Wouldn't it be great if we had Exxon's or Chevron's first 3-4 years worth of numbers and then multiply inflation factors up to 2012 and compare it to TECO's numbers so far.  I imagine that the E&P science, machinery, process, etc has changed so much since those days that it wouldn't be a very close comparison.  I see in the spreadsheet example how they started with $10mm investment costs and after year 8 ended up with $19.2mm cash flow after all costs so $9.2mm return or approx. the 100% they like to target.  How in the world would TECO become cash flow positive so quickly with all their lease, equipment, and other ongoing expenses?
