No. In my case, I only verify whether the WIF (Wallet Import Format) is correct. The output displays only checksum-validated WIFs. The second script computes the corresponding public key and address.
How many verified WIFs do you have in the output generated by the GPU?

It depends on how many characters are missing in the WIF and their exact positions. For example, if 10 characters are missing at the beginning, the recovery speed would be approximately 2,000 valid WIFs per minute.
