It's little more complex than just "highlighting the numbers"; in my opinion, there really needs to be a definition of what is being counted and how that's universal within Indie Hackers presentation of startups.
For example, three identical startups using different accounting methods (cash vs accrual), time periods, etc. would have at face value potential vastly different numbers, though the reality is they are identical in every way.
And on a meta-point, I appreciate the effort, honesty and transparency you put into IndieHackers, it's a great resource for me.
