Yes, but sometimes switching to arithmetic/absolute thinking is the right thing to do.
For example, suppose an engineer who is paid $200k per year can spend a week to implement an optimization that reduces costs by 0.1%. If that is 0.1% of something that costs $50 million per year, then that's not a bad use of time.
