So using the achievements, we're looking at ~50 hours being 7 capstone upgrades and level 90+ being 100 hours.
It's interesting that they're using % here because it avoids using actual numbers and hides away the low sales of the game. We know that this pretty much only sold to sweats, so claims of high % means shit when your player base total is tiny. There's a certain someone who likes to make long posts of game comparisons who I also notice uses % to hide away the numbers. 80% drop in user base is typical right, but when one game starts at 500k CCU and the other at 80K those drops don't tell the full story.
