Is this ok, what about other keys am I actually training them or just the heatmap is off... ?
Mine looks almost exactly the same and I have a custom wordlist.
If you want a more balanced word list, you can make one and paste it in the custom text field under settings. Keybr specifies in the instructions that it tries to create words that are similar to english because the author believes it to be more helpful for the majority of users (and I think they're probably right, but I've done/read no studies on it so I don't want to commit)
The real question is whether you feel that in your left hand or not. Maybe the backspace and mouse are keeping your right hand busy enough that it doesn't hurt unevenly?
