Too many bad predictions - easy fix

In past 3 yrs my typing experience with SwiftKey has been steadily deteriorating (I use it for 5 yrs or so). If you add new feature I am about to ask it will eliminate at least 50% errors in prediction and arguably improve learning of your models. For unknown reason I seem to hit Space by mistake too often. A lot more than it's reasonable to assume. For example I am typing "I think" and I end up "I the hink". In many instances completely random 3-4 words pasted in the text. I think - if you add a setting where users can change distance between main keys and space would solve it
