I want you to know this comment is every bit as subjective and "not helpful / convincing" as you think mine is except mine had deductive reasoning -- yours is just anecdotal. I only been coding for 10 years, so maybe some veterans who been coding since the 70s can share their experience and we can weigh it against yours.

I also question that you indeed are a faster scanner. Here's a specific example I wonder if your scanning would win out on -- Xcode turns internal Cocoa classes blue whereas your own classes are green. You quickly know what you coded and what you didn't. Not helpful? Should already know? I wonder if you inherited someone else's code base if you would enjoy the green immediate feedback rather than the inference you would otherwise have to take.
