You are right. The reason why I had the acceleration problem was my
acceleration weight was 0.5!
0.5! 0.5! That was why I had hard time on doing acceleration :)
The minimum weight value was 0 so I could change that to 0.5.
Now I set the minimum acceleration value to 1.0 from elementary_config.

So it's fine to me and to anyone else.
Thanks.
