羽毛球成本计算Shuttle Cost Calculator

一筒多少钱、一场用掉几个：看每人每场花多少，一筒能打几场。What a tube costs and how many a session uses: see what each player pays, and how many sessions a tube lasts.

选型号时按哪边官网的标价填：人民币是 Yonex 中国的，美元是 Yonex 美国的。胜利官网的常规球都没标价。Which store a tube’s price comes from when you pick a model: yuan are Yonex China’s, dollars Yonex USA’s. Victor’s site prices none of its regular tubes.

一筒多少钱Price of a tube选了型号，先填上厂家官网的标价。你买的价格多半更低，改成你实际付的。Picking a model fills in its maker’s list price. You may well pay less: put in what you paid.

一筒几个Shuttles in a tubeYonex 美国和中国官网都没写一筒几个。胜利中国写在「单位」里：「打」是一打 12 个，「1/2 打」是 6 个，也有「3只装/桶」已核实。Yonex 日本官网的羽毛球大多在名字里标着「1ダース」（一打），尼龙球标着 6 个或 3 个装已核实。官网没写的，数一数你的筒。Neither Yonex’s US nor its China store says how many a tube holds. Victor China gives it as the unit: a dozen, half a dozen, or three to a tube verified. Yonex Japan names most of its feather tubes as a dozen, and its nylons as sixes or threes verified. Where it isn’t given, count yours.

一场用掉几个Used up in a session一场下来打坏、打飞，或者飞得不好换掉的，一共几个。厂家都没给这个数未知，你们自己最清楚：开场前和散场后数一数筒里少了几个，打几次取个平均。How many a session gets through: broken, lost, or swapped out for flying badly. No maker gives a figure unknown, and your group knows best: count the tube before and after, and average over a few sessions.

B 可以不填；填了就和 A 比。B is optional; fill it in to set it against A.

几个人分Players sharing一片场打双打是 4 个人，单打 2 个人。Doubles on one court is four players; singles, two.

每周打几次Sessions a week用来算一个月和一年：一年按 52 周，一个月是一年的十二分之一。填 0 或者空着就不算。For a month and a year: a year is 52 weeks, a month a twelfth of it. Put 0, or leave it empty, to leave them out.

羽毛球还是尼龙球Feather or nylon

点开每一格看规则和厂家怎么说。Open each tile for what the Laws and the makers say.

世界羽联规则第 2.1 条：球可以用天然材料或合成材料做；不管用什么做，飞行特性大体上要像软木球托外包薄皮、插天然羽毛的球已核实。BWF Law 2.1: a shuttle may be made of natural and/or synthetic materials; whatever it is made of, its flight should generally be like a natural feathered shuttle with a cork base covered in thin leather verified.
规则第 2.2 条：16 根羽毛插在球托上，长 62–70 毫米，整个球重 4.74–5.50 克已核实。Law 2.2: 16 feathers fixed in the base, 62–70 mm long, the shuttle weighing 4.74–5.50 g verified.
规则第 2.3 条：不用羽毛的球，用合成材料做的裙边代替羽毛；尺寸和重量照羽毛球，但因为材料不同，可以差 10% 以内已核实。Law 2.3: a non-feathered shuttle has a skirt of synthetic material in place of feathers; its measurements and weight are a feathered one’s, but as the materials differ, a variation of up to 10% is acceptable verified.
胜利把毛杆用碳纤维、毛叶用 LDPE 塑料做的球单独归为「人造球」（比如 NCS 新碳音、CS 系列），和鹅毛球、鸭毛球、尼龙球分开已核实。它们耐不耐打，官网没写未知。Victor files shuttles with carbon-fibre shafts and LDPE plastic vanes as a kind of their own, synthetic (the NCS and CS lines), apart from goose, duck and nylon verified. How long they last, its pages don’t say unknown.
Yonex 美国说 Mavis 尼龙球的飞行接近羽毛球，耐打是普通尼龙球的最多五倍已核实。注意它比的是别的尼龙球，不是羽毛球；一个尼龙球顶几个羽毛球，没有厂家给过数字未知。Yonex USA says its Mavis nylons fly close to feather and last up to five times longer than standard nylon shuttles verified. Note that it compares them with other nylons, not with feathers; how many feather shuttles one nylon replaces, no maker says unknown.
Yonex 中国把 Mavis 300 标成「耐久型」，Mavis 600 标成「飞行稳定型」已核实：厂家自己就把耐打和飞行稳定当成两种选择来卖。Yonex China labels the Mavis 300 a durability type and the Mavis 600 a flight-stability type verified: the maker itself sells the two as a choice.
速度不对，球不是打短就是打长。Yonex 说：天热、空气稀，选慢的（号小）；天冷、空气密，选快的（号大）已核实。按场馆挑速度，用球速选择器。At the wrong speed a shuttle flies short or long. Yonex: slower ones (lower numbers) for warmer, thinner air, faster ones (higher numbers) for colder, denser air verified. To pick for your hall, use the speed picker.
这里的价格都是 Yonex 自己官网的标价已核实。胜利官网只给几款纪念版标了「建议零售价」，常规球都没标已核实。很多人买得更便宜，按你实际付的填估算。The prices here are Yonex’s own stores’ list prices verified. Victor’s site gives a suggested retail price only for a few limited editions, none for its regular tubes verified. Many people pay less, so put in what you paid estimate.

一场用了几个，怎么数Counting what a session uses

开场前数一下筒里有几个，散场后再数一次，少了的就是这一场用掉的估算。Count the tube before you start and again at the end: the difference is what the session used estimate.
每场用得不一样：人数、水平、球的新旧都有关系。记三四次，取个平均更准估算。Sessions differ, with the players, the level and how new the shuttles are. Note three or four and take the average estimate.
羽毛断了、飞得歪了被换下的，虽然没坏透，也算用掉了估算。Shuttles swapped out with broken feathers or wobbly flight count as used, even if they aren’t finished estimate.
