My concern is that it's always harder to comprehend and debug code you didn't write, so there are hidden costs to using a copy-pasted solution even if you "get to the testing phase faster." Shaving percentages in one place could add different ones elsewhere.
Imagine if your manager announced a wonderful new productivity process: From now on a herd of excited interns will get the first stab at feature requests, and allll that the senior developers need to do is take that output and juuuust spruce it up a bit.
Then you have plenty of time for those TPS reports. (Now, later in my career, I have a lot more sympathy for Tom Smykowski, speaking with customers so the engineers don't have to.)
