How to create a correct entity-relationship diagram (ERD) about a video game profits scenario
A question I have is what is the significance of the _EK/_ED columns? I can assume they are separate columns for each person in your party? If that is so, this design would have a lot of NULL values for whenever there isn't 4 people in a hunt, and will outright prevent accounting for a 5 person hunt. I hesitate to suggest a more flexible design until I can better understand what exactly each column is for. I would be happy to expand on what you have if you could post some sample data, such as from a hunt or two, along with a quick explanation of where the information is coming from.

I would also review the datatypes chosen. SMALLINT is fine for key id fields, but it would be best to choose a DATE or DATETIME for your hunt date, instead of varchar. The Paid column has two issues that I see. Including a question mark is not encouraged, instead keep it to alpha-numeric and maybe underscores. If the only two options for that field are Yes/No, then it can be a bit datatype. That way you only store 0 for no, and 1 for yes. That saves a lot of space compared to varchars, and prevents you from having "Yes","YES", and "yes", which are all seen as different depending on your chosen software.
