Here's where all of the critics of Dice Influencing and Dice Control can state their reasons why DI is not possible or why people can't become dice influencers or dice controllers.
I'll start, because I've been playing craps for 20+ years and I have a pretty good handle on what's involved in throwing dice.
Here are my top 3 reasons why it's hard or impossible to influence dice:
1. Most people don't have the fine motor skills. To influence dice you must be able to toss two dice to a predetermined point on the table layout with just the right amount of pressure (force, speed) and control of the dice movement in the air, so that they gently hit the back wall and do not bounce off the back wall with too much rebound or movement.
2. Repeat of #1.
3. Repeat of #2.
