Right now on account of these three experiments alone, we have a very wide spread in ratios. Dividing by zero is not defined. I suspect there will be other experiments that give a different ratio. This is not to say that the ratio is not in fact stable; perhaps it is. I'd like to know whether it is rather than assume in advance that it is. It's a question: is the ratio stable? Eric
