Interesting approach. Did you ever try to include other factors into the model ? Such as :

  * cost of sales (and crm, and billing)
  * cost of infra
  * taxes (on income and profits)
  * taxes (on salary)
  * cost per employee (office, PC, software licenses)
  * cost of loans needed for the investment

Would be curious to see how big the ratio remains.
