1. It's rare that I have to use Google figure out how to do basic tasks in my Programming Languages of choice (C#, & TSQL). Don't get me wrong I, and everyone on the planet, looks up code on the internet. It's just a more rare scenario for me.
2. I write much quicker then your average developer. Of course most of software development is design and requirements gathering/clarification but when I do get down to writing code I'm very fast.
3. I spot bugs almost immediately because when I go through my Anki deck I get repeated exposure do different error scenarios. In fact I can often simply think about the scenario and it will occur to me where the bug is and what is going on. I attribute this to using Anki on a daily basis.
4. I can read code much better then before I started using Anki. I know at a glance what code is part of the language/framework vs what is custom code for the application.
