Why is there such a big difference in the credit received vs credit claimed for rosetta@home while other projects like Einstein@home they just about match (shown below in bold Claimed followed by granted)?

Because these projects use different methods to calculate the credit. BOINC credit isn't normalized between all projects, probably never will be. There are projects that give you high credit, there's projects that give you low. Some still use the old method of benchmark * run-time, some just have values set in the database, others use CreditNew calculations.

The newer BOINC back-end software doesn't show the claimed credit anymore.
