You shouldn't care about your spar stats. Just spar the toughest opponents and beat them or come close. People will notice you eventually. Some people have terrible stats and are really good. Some people have amazing stats, but selective sparred to get them so they are not at the skill their stats are. Bottom line, spar for fun not for stats.
BTW: if you boost to get reset, only your wins will get reset. Your losses will remain the same. So do you prefer 1000-2000 or 0-2000? Up to you.
