Where are stats stored, how to reset them and/or stop them being collected

I am using cloudflare and easycron, so I run warmcache pretty frequently. Here is the current display:

————-
Crawled in total 25105 pages in a total of 9115.9825029373 seconds
Average page to load a page in seconds: 0.36311422039185
————-

I disabled the enormous stats display on the warm-cache.php page by commenting out the table code in the plugin. However, but I would much rather have the plugin collect maybe the last 20 runs or not collect any stats at all.

How would I accomplish this?

Thanks!
