To some extent I think you guys are losing the forest for the trees. As far as I can tell, the newest scoresheets being shown don't resemble either the American or the European system too closely. An analogy would be if these two cultures were trying to communicate, your answer is inventing a whole new language, rather than to just choose one of the existing ones and have one side learn it.
Both original styles work pretty well; it's only a matter of a few small tweaks, isn't it?
If these new versions are intended for the serious AZB member to keep track of his practice runs, I can see their value. Many of the AZB members would like to see as many possible statistics of their play as they can, and (most importantly) will take the time to learn a new system. I am also tempted to say the average IQ on this board is probably somewhat higher than that of the average poolroom

.
I do not think these new systems are going to be adopted by the pro players in tournament conditions, because all they want is a system that lets them keep their minds on the game. In the last 14.1 championship, I had such problems reconciling my scores with Gilliano Schmidt's that, after much exasperation, we just got someone else to score the match for us. It was taking too much energy trying to deal with the scoresheet. And that was with each of us scoring the matches as we each knew how - can you imagine the difficulty we would have had if
neither of us knew how to use the scoresheet?
This is only my opinion, and I have been trying to hold my tongue because I know that several of you are working very hard on this. But it seems with each new iteration, the sheets are becoming more and more foreign from anything we've ever seen before. Even if the new versions worked better than anything we've had previously, there's an "adoption" problem with things so different. If they're so different that they border on intimidating, my prediction is no one will use it.
