I made a video on how to use the bead scoring system. I hope everyone likes it. Remember, I do not do this for a living....LOL... I did my best.

Thanks for doing this -- I've been thinking about writing something up for a while.
There are some tricks/techniques you might add if you redo it:
When I leave the table after a miss, I say something like, "6 left" so I know how many rack beads ought to be on the wire (9) after I finish adding to my score. Alternatively, I might say "9 gone". This allows my opponent to check my count and speak up if I got it wrong.
To get to the count on the table, I count by either 3s (if I'm tired) or by 5s if I can picture the lumps of 5 quickly. I'll also do the count when I figure my opponent is about to miss or play safe so I'll be ready with the score.
When moving beads, it's very useful to remember that if a group of beads has off-color beads on each end, it is either 6 or 11. If I have to give myself 13, that's often a group of 11 with two extras on one end or the other.
If you just miss an off-color bead being in a group, then you know that you can count by 5s. You can count from either end of the group.
I try to announce "one away" when I'm scoring a foul. If I run some and scratch after making a ball, I'll spot the ball up, say something like "seven left" then "one away" as I take one from my total and then maybe "five total for me".
I'm the impatient kind when it's my turn to shoot, so I get a little irritated when my opponent counts out 12 beads one bead at a time when there's obviously a group of 11 with hangie-down-dealies on each end plus one more bead. I try not to yell at slow scorers.
I have a different way of scoring fouls at the start of the game, but most people do it the way you showed. Mine is based on the fact that having -3 total looks just the same as 47 or 97.
