That's not too far off. I think technology is driving productivity. I can do things in 30 minutes now that would take a designer a week to do just 5 years ago, due to more automation and better design practices.
The point is to manage expectations, and alway barely meet them. If you don't meet them, it reflects poorly on you. If you exceed them, you will get more work and higher expectations, until eventually you don't meet them. The worst thing you can do is finish ahead of time, because your reward will be more work.
