Like I said before given the fact that each and every one of those locations is mutually exclusive to the rest they will have to check the remote possibility of ONLY 1 out of those 4 verified pings could be the REAL THING.

You're quite right!

The underwater search has been narrowed to a circular area with a radius of 10km (6.2 miles) around the location from which one of four pings believed to have come from the recorders was detected on 8 April, officials said.

The current refined search area was based on one such transmission.

Which one? And why did they home in on this particular one? Do you know which one of the four it is, Pyro? Can you tell from the signal-noise charts you posted, why this one possibility would be better than the other three?

They are concentrating on all 4 detections in turn.

Naturally, the I ritual detection was for over 2 hours before they lost it so they will focus on that first. But, eventually they will survey the entire area of some 1100 sq kms and if be essay expand the search area.

They haven't even scratched the surface. They have a long way to go.

They have also announced that more Bluefin-21 AUVs will be deployed to the area as confidence grows.

Also another more capable RUAV to be deployed which is capable to retrieve parts of the wreckage and a Black Box.

Furthermore, Pyro, logical deduction would suggest if the pings were all equally likely (and hence equally unlikely), that just searching one area would give them the answer. If there is a "best fit" and they exhaust the search in that area and it proves negative, then there is no logical reason to search the "lesser fits". Right? So they must have ONE ping which they preferred for some reason.

And of course, that seems to be what they are doing, certainly NOT raising hopes that they will search the others - searching only the one area from which to draw a conclusion as to the reliability of the iffy "pings" seems sufficient especially when all the other "leads" have now been negated ...

The underwater search for the flight recorders from the missing Malaysia Airlines flight MH370 could be completed in five to seven days, Australian officials said on Saturday. ... Officials did not indicate whether they were confident this search area would yield new information about the flight, nor did they say what steps they would take if nothing was found.

A complete rethink is needed ...

They will look at all of them.

However, easy to presume the position of the 2 hour and 20 minute detection will be first cab off the rank.

Do you know which one that is?

No that is not the case! The will have areas which they would deem more likely than others based on the cluster and signal strength and length of time.

However, all pings are within the same search area of some 1100 sq kms which they will cover every sq inch of!

Also each Bluefin Mission will have a 40 sq km area to survey and each subsequent mission will overlap on occasion.

That's caput. Already done 1 and 2.
