For these examples - result is instant.
I have made test with 10 missing characters (CPU only, on my dev machine I do not have GPU).

Code:

Range: BigInteger.valueOf(58L).pow(10).toString(16) =

Fake end: new BigInteger("0552e02556fb5aeb9aedc2ea64efec8ac200eb71a9653cfaad25d4c2a5b4d5c7",16).add(new BigInteger("5fa8624c7fba400",16)).toString(16) =

Not bad, no? Wink

10 missing WIF characters - Less than 11 minutes on old CPU. GPU performance - to be seen.
