Pat,
to say to a common person 2+2 is a notice.
To add , after, 2+2=4 would seem an insult against his intelligence.
To say it to a scientist goes more over.However you see a question where it isn't.
I provide a city name or zone if you think it is a courtesy, I follow always the good advices.

Time ago, I sent you an e-mail in which I spoke about 100%, let you understand me, I wished to say that only the signals received have this occurring to 100%, as to say:
if, for example, in a year I receive only two signals of 4.0, you'll see only the occurring of two EQs of 4.0. If in a year I feel zero signal, there will not be any EQ.
Tu comprendere? Io sperare si.

For further clearness: about the sequence of EQs in Italy (Emilia), on this month, I knew to 100% that it would be occurred like sequence, but the place was to 33% (Lazio-Emilia-Greece). To day, with this new experience, if I had receive the same signal, the percentage naturally will get up 70/80% to a before look.
