3 is roughly half of ten logarithmically. And in any business that uses software (to co duct the business) you always want engineering to keep in mind the doubling time, or if the business is shrinking. A lot of efficiency decisions are driven by doubling time. I worked where we had doubling time of 90 days when I started and there keeping everything scaled up so that your idle capacity was. On more than half made sense. When it had increased to a couple years, then your could tighten down to n/n+1 utilization. If it is shrinking, first of all that's a problem, but also you can make the infra much cheaper pretty easily, if the code is still modifiable.
