Yes.  Last week I made available hundreds of exponents that had previously
been tested.  These LL tests had errors detected during the first run.  History
has shown that in roughly half of these cases, the final LL test result is
incorrect (prime95's error checking cannot catch all errors).

My goal is to get at least one clean run on each exponent as we march
higher.  At worst we get an early double-check, at best we find a new
Mersenne prime without waiting 2 years for double-checking to get this high.

Have fun,
George
