Here is suggestions, do it if you want:
1. A cvar for add if the owner/admin want to the plugin reset all status after one month, two months, 1 week, 2 week, will not be bad.
2.
PHP Code:
server_cmd("echo Stats Reseted")
Is this really necessary ?
3. Add a log adding the current day, example:
PHP Code:
log_amx("The stats has been reseted today: 08/12/2016")
