No need to explain the background here. Just say what it is accurately. For this
one, it will be

<summary>
  The total number of HTTP responses that have been checked for tampering. This
assumes a data reduction proxy injected fingerprint is not tampered. Only data
reduction proxy responses with 200 OK response code are checked.
<summary>

Please double check if this is faithful to your implementation and apply wording
for all the others.
