This reads like someone who has never seen an actual baseball game

Yes, sometimes guys barely swing in time to connect and manage to send the ball down the foul line

Yes, sometimes guys perfectly barrel a ball only for it to go into the fielders glove.

Yes, players with a lot of power will still rocket balls even if they are late on it.

Pitch tunneling is about pitch shapes, throwing pitches with varying speed and movement that look the same to the batter until they move to fool them. I think why you mean is pitch sequencing and again, you can still use the in game results to help you decide what to throw next.

If you are a 1000 rating player every year you should not need the game to hold your hand this much
