在武术赛事中（尤其是拳击），我们提供涵盖 5 分钟回合的无风险投注。 不同的博彩公司可能会根据各自的规则采用不同的回合计算方式。 目前主要有三种回合计算方法：
Incomplete/Started Rounds
If a round begins, it is counted, even if the fight ends prematurely.
By-Time rounds
A round is counted if more than half of it (2.5 minutes) has passed. For example, if a round ends early due to a stoppage, it may still be counted as complete if more than half of the round elapsed.
Full/Complete Rounds
Only fully completed rounds count toward the total. If a fight ends early, the round in which the fight concluded is not considered.
重要提示：所有三种回合类型的投注结果均由半点（0.5 回合）来决定。
对玩家而言可能存在的风险：
Our service may sometimes misinterpret certain 'incomplete' or 'by_time' markets as 'complete.' We therefore suggest that you carefully study the bookmaker's rules regarding the total of rounds before placing a bet. If the rules are unclear, please contact their support team for clarification. If a bet is settled differently from what was stated in the arbitrage opportunity, contact us immediately. Provide screenshots of the betting slips, bookmaker rules, and support correspondence for further investigation.
最后但同样重要的是：
理论上，我们本可以生成结合了已开始回合和完整回合的无风险投注（请参见下方截图）。 由于 "全回合低于 1.5" 市场仅计算完全结束的回合，如果比赛进入第三回合，该投注将会失败。 如果发生这种情况，"已开始回合超过 2.5" 的投注应当获胜。
这种无风险投注的问题如下。 大约 1% 到 5% 的比赛以 RTD（裁判技术性判定）结束 —— 也就是说，比赛在回合间的休息时段被中止，原因可能是拳手一方的教练组决定终止比赛，或者运动员本人拒绝继续比赛。 在回合间的休息时段，三种回合计算方法的结果是相同的。 因此，上述无风险投注中的两项投注都会失利。 因此，我们不提供此类无风险投注。
