it is only correct in its conclusion that I mistyped a word about 10% of the time
I'd love to see your statistics on that - you must use a lot of very unusual words. Google has published a paper about the algorithm they use.
There are two cases:
If Google thinks you might be wrong it will display "Did you mean..." with the possible correction.
If Google is pretty sure you are wrong, it will search for what it thinks is correct and show what you typed originally as an option.
If you are hitting the second case 90% of the time then you are a very, very special snowflake indeed!
I have to go back and explicitly tell it that I meant to tell it what I told it
