Maxed boxing is really iffy, and like all staking you need to get first hit. I used to have a very good connection with world 22 when I did my staking, unfortunately everyone progressively emigrated to world 54 which is a sad thing because I lag like a bitch while entering a duel there.
People have different switching methods, and even with the knowledge of old school switching methods and a maxed account I still seemed to be losing 6 or 7 fights out of 10 while I boxed and about the same while rapier staking.
When you're not maxed though, stats and skill do come into play. it's like 70% luck, 20% stats and 10% skill.
I wish you luck staking. Just remember not to stake what you can't afford to lose, and know when to walk whether you be up or down.
