@grahamperrin That's fair. You're right: I can't understand a point you deliberately haven't made, and I shouldn't pretend that I do.I was responding to what I thought your concern might be, and explaining why the rule exists. But if that isn't the point, then I won't try to guess what it is.You are absolutely free to make that point, including if it is a criticism of the rule or of my decision to introduce it. Disagreement with the rule is not against the rule.And if you'd rather not elaborate, I respect that too.I still genuinely regret seeing you leave, but I don't want to turn this into an attempt to convince you to stay.
