IMHO, you've gotta do everything in your power to make it as difficult to cheat as possible. Glad to hear that you're honest about your approach to the sport, but sadly, there's simply no guarrantee that everyone who attends these OPs have the same sense of honor. If everyone were that honest we wouldn't have to chrono at all and you wouldn't see the occassional high level of frustration in other players when they suspect their opponents may not be calling there hits (but that's another matter). Point is, you can't be sure everyone is 100% honest and therefore everyone must be held to the same strict standards which includes chrono procedure. While you were shooting high but only using 0.2g BBs, someone else could have said the exact same thing but were in fact lying and really using 0.36g BBs.
