I find it kinda ironic that this is coming from a PM.

Software is an area where you can get absurd productivity gains just from having different task definitions, by simplifying things where they can be simplified, or by simply planning better. I've seen plenty of bad PMs making a team work 2x, 3x, 4x more to accomplish something, purely because of unimportant details that ended up being too much trouble.

Not to mention I've seen countless times teams growing from say, 2 to 10 developers and not having even close to 2x difference. Heck, half of Mythical Man Month is about that.

So yeah, amount of time doesn't correlate to amount of work. And especially doesn't correlate to amount of value delivered.
