How many total reports have you made both recently and overall?
I have reported 201 posts with 94% accuracy.I don't know how to distinguish them.
Hmmm, it looks like you have somewhere between 187.935 and 189.945 correctly reported posts. Your accuracy should increase to 95% if you were to report three additional post that are
marked as good by the moderator that handles the reports. Some of your recent reports (or some of your reports overall) may have been "
ignored" by the moderators, and until your report is either marked as "good" or "bad" it will not count as part of your calculation for your accuracy.
It is possible that some of your more recent reports were "ignored" by the moderators, which would explain as to why your accuracy has not changed.
The reason why I asked how many reports you have made recently, is because if you have only reported a small number of posts recently (since you originally noticed your accuracy is 94%), then the simple explanation as to why your accuracy has not changed is because you have not reported a sufficient amount of additional posts to increase your accuracy rate based on how the system rounds.

. Just keep reporting and as long as they're handled (or not marked as bad) it'll go up soon enough.
