A Host Score helps determine how reliable a host is based on how many tickets they have sold across all of their previous competitions.
If a user hosted 1 competition and sold 100% of their tickets, their Host Score would be very high. If a user had hosted 10 competitions and only ever sold 1% of the tickets in each of them, their Host Score would be very low.
The score is calculated based on the overall percentage of tickets sold in relation to the total number of tickets issued.
By default, all featured raffles are displayed in the order of the highest Host Score first.
