I find that if you type out the whole word, by swiping or individual letters, no matter how inaccurate your presses or swipes are it can guess the correct word with high accuracy. If you instead type out only a little bit of the word its ability to guess is shockingly bad. So it’s better to scatter gun the whole word than try and type accurately but only type the word partially, if that makes sense.
What annoys me is that I swear it didn’t use to take me trying to type the whole word before it guessed the correct word. So something has changed, yes.
