STATISTICS
In this area it is possible to calculate some statistics about the motorbike, the real total amount rate per mile.

Statistics are calculated everytime on Database information, graphs are showed filtered by year.

To view statistics and graphs there must be at least 1 record for every single tables: (1) original cost and one used evaluation (2) one maintenance record (3) one "other costs" record (4) one month mileage.

Statistics and graphs for a specific motorbike are calculated as follow:

Total miles: Sum of all mileage in months and years and the "start mileage" on the top of the "month miles" table.
Miles/year forecast = average mileage made in months and years for one year.
Total maintenance = Sum of every maintenance amount in the database.
Total costs = Sum of every cost amount in the database
Out of pocket expense: Sum of Total maintenance and other costs.
Out of pocket expenses = Sum of total maintenance and total costs
Total devaluation = Last "new" amount - last "used" amount (there should be only one new amount)
Total amount = Sum of total maintenance + Total costs + Total devaluation

Every single value is also divided for mileage to calculate it's rate.
