Why Create an Account?

The main goal of this site is to provide information about the TREFF-model. This is a personal project that shows how the TREFF model works. If you follow the learning steps, you will see that for most interactive calls with the TREFF model, you need to log in.

Why? Simply because it costs money to keep the site up and running. If everyone keeps pressing the buttons to calculate, the costs will be enormous. By using a restriction, people can learn for free.

What Happens When I Create an Account?

If you register, you can log in to the website and start using:

• All the interactive learning pages.
• Download the data produced by the calculations.
• Over time, more functionality will be added.

The number of calculations each month is limited but can be increased if requested by our administrator.

Are You Planning to Make it a Paid Site?

No. This is a hobby project. Of course, it would be nice to have some extra income, but I believe that for learning purposes, a donation is more than enough. Therefore, I added the "buy me a coffee" icon in the bottom right corner of the page.

Commercial Use of the Math?

I work at the company DutchWorkz, so I can't work more than I already do.

Currently, DutchWorkz is looking at ways to help a cycling team, so yes, there probably will be a dedicated version of the mathematical TREFF-model. It's too early to tell what parts can be used later for others, but I hope the model will become more mainstream later on.

By working with my boss, I can make a clear distinction between my hobby and my work. I'm also able to focus solely on the learning content of this site.
