Just to mention it, the appendix A.3 of this document shows the individual results of _each_ provers and for each algorithm.
It is interesting to observe that, in most cases, Alt-Ergo, CVC4, CVC4, and Z3 have very *closed* results, and Eprover is significantly aside.
In the table provided by Jens, most provers (except Eprover) completely verify all the verification conditions but a few.

A possible next step would be to extract the « difficult » verification conditions and understand what is going wrong with them for each prover.

Second remark, regarding WP, it would be interesting to compare the results obtained with its native support of Alt-Ergo, or via the Why-3 translation.
Namely, comparing -wp-prover alt-ergo and -wp-prover why3:alt-ergo in order to understand the impact of Why-3 translation.
