With stadiums having a potential effect on match results, it's assumed that home/away matches would automatically be distributed as evenly as possible in a league. But at least for round-robin, that is not the case. There are several examples in our league of a team getting 6 or 3 home matches (instead of 4 or 5, which would be as even as is possible).
I'm assuming this is a bug. If it isn't, consider this a suggestion to change it so that the distribution is even. Thank you.
