Is it possible to easily remove all hits from a given IP on a given day?

I ran a penetration test on my site the other day which racked up tens of thousands of hits from my IP and they are significantly skewing most of the statistics.

I would like to remove the hits from that IP for that day from the SS DB, but I could not see any obvious way to do that though the SS frontend and looking at the SS DB, it wasn’t immediately clear where I could manually implement the removal.

I guess my question is two-fold: 1) If I missed something on the frontend, can you point me in the right direction? 2) Failing 1, can you tell me how I might go about manually removing the hits from the DB?

All the best!
