The account system will help to validate the data being submitted. I want to ensure any data recieved and used in caluclations is as accurate as possible. For this reason I will be splitting up the results into two categories: "Dirty" and "Clean". Users who create an account and use that to submit data will have their results marked as clean and users who do not log in to submit will have their results marked as dirty. This allows me to accept any submissions regardless of wether or not the user created an account while maintaing a relative balance between validated results and anonymous results.

What good is having data that is not easy to look at? The plan is to create an interactive graphing system that will allow users to look at data sets based on specific criteria to compare or contrast different information.

Surveys are a very useful tool for gathering specific information. Since logged in users will have their test results saved, every survey they complete will provide more information to compare to others of all types. This could allow for harder-to-discover similiarities and differences among the types to be noticed.
