半分计算器 - 盘口投注买卖分数
免费半分计算器用于NFL和NBA盘口投注。查看买入或卖出半分如何影响赔率和派彩。
如何使用此计算器
- 输入当前的分差
- 输入当前分差的赔率(美式格式,例如-110)
- 输入如果您购买半个点的赔率(例如-120)
- 查看隐含概率中的成本以及购买半个点是否值得
公式
从美式赔率得出的隐含概率:
- 负: |赔率| / (|赔率| + 100) × 100
- 正: 100 / (赔率 + 100) × 100
半点成本 = 隐含概率(半点赔率) - 隐含概率(当前赔率)
如果成本 < 比赛落在该数字上的概率,则值得购买
常见问题
What does buying a half point mean?
Buying a half point means paying extra juice (worse odds) to move the spread by 0.5 points in your favor. For example, moving from -3 to -2.5 eliminates the chance of a push on exactly 3 points.
What are key numbers in NFL betting?
Key numbers are the most common margins of victory. In the NFL, 3 is the most important (~15% of games), followed by 7 (~10%), 1 (~6%), and 10 (~5%). Moving off these numbers is generally more valuable.
Is it usually worth buying a half point?
It depends on the number. Buying off 3 is almost always worth it at standard prices because games land on 3 about 15% of the time. Buying off non-key numbers is rarely worth the extra cost.
Does this work for NBA?
NBA margins of victory are more evenly distributed, so no single number is as important as 3 in the NFL. Key NBA numbers are less pronounced, making half-point purchases generally less valuable.
