Features:
1 Operation as simple as possible, all the module one-touch access
2 Input as simple as possible, targeted self-made keyboard, smart judge
3 Fuel-related statistics feature-rich, add, modify, delete function is perfect
4 The chart is simple and practical, drawing two-coordinate
Limitations (for the daily needs of most users, considering the case of the flexibility and simplicity):
1. This version is only concerned about fuel consumption and related statistics, are not concerned about parking fees, maintenance fees, insurance premiums and other costs
2. If the data records are very few,the statistics are biased
3 For the simple of operation, regardless of actual driving in extreme cases. Such as the odometer over one million, the oil price over a million and so on.
Statistics Description:
1. the first record is just a benchmark record for statistic.
2 Total Fuel = The last record + … + The second record . (The first record is not included in statistics)
3 Total Payout = The last record + … + The second record . (The first record is not included in statistics)
4. Total Mileage = The last record - The first record
5 Total days = The last record - The first record
6 Avg. Consuming (Average fuel consumption) = Total Fuel / (Total Mileage / 100)
7 Avg. Payout (Average fuel costs) = Total Payout / Total Mileage
8 Avg. Mileage (The average Mileage) = Total Mileage / Total days
9 Avg. Price (The average oil price) = Total Payout / Total Fuel
10. Daily pay = The payout of this record / (The date of this record - the date of the previous record)
11 Daily miles = (The mileage of this record – the mileage of the previous record) / (The date of this record - the date of the previous record)

特点:
1.操作尽可能简便,所有功能一键直达
2.输入尽可能简便,针对性自制键盘,智能判断
3.油耗相关统计功能丰富,添加修改删除功能很完善
4. 图表简洁实用,绘制双坐标
局限(在考虑绝大部分用户的日常需求的情况下考虑灵活性与简便性):
1.此版本只关注油耗相关统计,不关注停车费、保养费、保险费等其他费用
2.在油箱是否加满的情况下,如果数据记录极少,统计数据有所偏差,在数据多几条的情况下,则基本没有误差。
3.考虑到操作的简便性,不考虑实际行驶中的极限情况。如里程表超百万,油价过万等。
统计说明:
1.第一条记录仅为统计的基准记录。
2.统计以记录向上补充原则。即:本次加油,即考虑为在过去行驶中已经消耗(考虑为油箱的初始状态是满的,参照第一条)。
3.总油量 为 最近一条记录 累加至 第2条。(第一条记录不纳入统计)
4.总油费 为 最近一条记录 累加至 第2条。(第一条记录不纳入统计)
5.总里程 = 最近一条记录 – 第一条记录
6.总天数 = 最近一条记录 – 第一条记录
7.平均油耗 = 总油量 / (总里程 / 100)
8.平均油费 = 总油费 / 总里程
9.平均里程 = 总里程 / 总天数
10.平均油价 = 总油费 / 总油量
11.日里程 = (本次里程 – 上次里程) / (本次日期 – 上次日期)
12.日油费 = 本次油费/ (本次日期 – 上次日期)
