My retention rate on mature cards floats around 70-75%. Yes, it does cut down on my review times. If the card is being failed too often because it won't stick then I'll look up additional info to add to its definition. If it still is being failed then it will get suspended, which is a good thing. I only pass a card if I get both the reading and meaning correct. I do press the good button too but only for new cards that are added during that session. The reality is that for some words a simple definition will suffice but for the majority of words you will not get a feel for them after just a couple times of seeing them in the wild; you need to see them used over a hundred times to be able to use them. After using Anki for so long you learn not to sweat the details too much because its a tool to help you and as soon as it becomes a burden to your study habits then you need to change it up. Keep it easy and consistent. Use other sources to that require less mental recall because it will be more beneficial in the long run. There is plenty of words that I know, that are mature in Anki, that I've read and heard so many times. But when it comes to speaking them, I can't get the right use down. Which means I need to see it used in many other contexts. One definition from Anki just doesn't cut it for practical use most of the time.
