SwiftKey is so awful with swipe and predictions for me

I don't understand. It's the same fingers on my hand. SwiftKey is system app / default keyboard on my Xperia X Performance. 

The swiping. Is so bad. Case in point. I could not swipe swiping in the previous sentence. Tried about 10 times. 

It's not only that. The words suggested to come next are usually meaningless. It doesn't seem to be learning or that ingredient.  They're I'm leaving in default words just so hit can see what is believing. 

Is they're any advice? I am having co luck. So you think it's my phone. It's the touchscreen so bad? 

Swype us better but I hate strain. Dragon.  I could NOT swipe dragon. That's another thing. The swipe hasn't a clue but start tap typing and lo and behold. 

Any advice is appreciated. Btw slowing down swipe is far worse.
