Cheers, Mike.
Thanks! I guess a question would be is this new analysis considered more sensitive in digging the signals out of the data, or perhaps it is just another way of approaching the problem, or perhaps it is analyzing data that has not been analyzed previously?
The latter. The S5 LSC Science run lasted about two and a half years, when we started S5R2/3 only the data of the first year was available. S5R4 is looking at the rest of the data from S5, where the sensitivity of the detectors was higher than in the first year. Also we got more usable data out of the second year, which improves the sensitivity of the analysis. That, however, also means that for the workunits the data volume has increased and the amount of computational work necessary to process them, too.

Point Reinhard to this thread or ask him via eMail. He did the major design of the S5R4 search and is pretty good in explaining these things.
If he hasn't got the time, contact Oliver Dreissigacker at AEI. He won't know from the top of his head but he will find out and explain.
And Bikeman is right, Einstein@home is not looking for binary systems, but just isolated spinning masses.
