With proper throttle control gain, your bike should be easy to control at low speed and not jerky with small throttle movements. The other purpose for these tables is to not give the engine more throttle than it can use (at lower rpm). With a proper throttle table, you can wack the throttle open and the engine will not stumble.
Here are throttle tables I tweaked a little from the H-D street tuner. I'm sure a lot of work went into this, H-D wants their bikes to have good throttle response and ride-ability:
I selected aggressive on mine witch is 3/4 of the way works great really happy with it just enough but not to much that ever time you hit a bump the bike jumps forward!!!
I have tried moderate & race options.....love both but my previous setup was guzzling gas like crazy so I kept it at moderate. Now my new setup, I have not mess with it and bike run strong without it....
