That's what I wrote 1st Pat, but I couldn't put the small numbers after it! Also, after I wrote it, I realised that it needs to be clear that there are two the same and one different and your equation implies that they are all equal but, in numbers, if W was equal to 1, then each x would be 0.33, but one is 0.34. Each x can be any other x at different times, if you get me.
POK, thanks for the help with the 1/0 and how it fits with the 2:1.
You made it easier to understand with the anything, everything and nothing.
