Yes, it is.
For BOINC a Theory (docker) task appears to be singlecore
=> aid.ncpus = 1
while Podman by default allows each container to use all cores of the CPU.
This leads to:
https://github.com/BOINC/boinc/blob/master/samples/docker_wrapper/docker_wrapper.cpp#L933-L936
    if (ru.cpu_frac > aid.ncpus) {
        print_once(string("stats command returned excessive CPU usage\n"));
        return -1;
    }
