Track your MTT sessions using a spreadsheet? Anyone have something like this?

I made this online spreadsheet from scratch. It started as a single table just to write down my daily sessions, but I've been working on it on my free time and right now it seems pretty good for me. I would like to know if you use something similar and if there are any improvements I could make.

Each day I clone the previous day tab and I add the basic data for a tournament, everything else is pretty much automatic and I can see how I performed.

And then I have a dashboard grabbing all data and showing useful stats.
