Meaning you would have to spend roughly 4 times as long on the mouse as you would have to on the tablet to get better after 4 stars.Where did you get 4 times as long from?
And well... you get the picture. There is a reason why pros don't use mouse.
Think of baseball.
You go on field with the intention to hit a home run.
You are given a hard plastic bat. (mouse)
Ball will never sail past the walls.
Now you are given a metal water loaded bat (tablet)
It will take some time getting use to the water in the bat but with some practice you'll be hitting homeruns often.
Except for the pros that do right?
I don't think this analogy is an appropriate comparison
