[Tropi]

Do keep going - this could be fun.

But the usual Tropi note of realism, which you are all welcome to ignore and probably will . . . if I were not I , I probably would too!
Come to think of it, even I ignore me sometimes!

OK, here it is - whatever number you think of is probably wrong in the tricky sense that, if the exercise were repeated (by someone who did NOT already know the first figure), it could be almost guaranteed that it would produce a different number on subsequent occasions.
So don't place any big money bets with Mop!

Tropi?
Who he?

Several reflexive remarks still up my sleeve but I'll save them and hope someone else, equally obtuse, saves ME from having to make all the acute cracks!

The concept is actually fascinating and I can see the need to know in a very practical sense. I suspect Fergy's barely perceptible and skilfully camouflaged edit may be closer than anything else . . . so far

Nah, dont!
Give it at least another day!
