Takeouts are only inaccurate when you use really heavy weight, same as in real curling. If one is going left and one right, then you are doing something wrong, it's not the game. 

I too agree, I believe that whole system is inaccurate at times on a shot basis not even an end basis. I you want me back to 40 from 200 then just put me there don't make it a slow death :)

However I believe the quality and frequency of shotmaking at peel weight could be increased with consistent curl across the board for everyone. Just my opinion.

As a matter of fact, all shots are inaccurate. The thing is that you can't compensate much with sweeping on the takeouts.
