I've been waiting for his answer impatiently. He's been active on other threads but completely ignored your post. Says a lot.
Well, what can one do :(.
Anyway, I must say I found the technique I used above quite effective at figuring out continous disagreements. You state some simple true/false statements describing your assumptions and ask the other party to agree/disagree and explain the points of disagreement. Apply recursively if needed. Kind of a discussion equivalent of git bisect ;).
Hey, I asked you three simple questions with pretty much boolean answers, in order to try and clarify where exactly you end up disagreeing with everyone. Please be charitable.
> Here's one of the suggestions: "multiply the last digit by the number of children and divide by ten".
Hey, that one was clearly meant as a joke, and is not the suggestion I was referring to. If something is a strawman here, this is. The one I asked about is the "My parents used the last digit on a stopwatch to decide which of the kids got to pick the radio station in the car and similarly trivial decisions. (If 0-9 couldn't be divided evenly among the kids present, leftover digits would result in a re-roll.)".
In light of that, could you provide the answers?
