There are some issues with player order in Match Play.
The "random" order option suggests that it will allocate player order, not choice of order. For other options, the descriptions in the software suggest that choice of order will be assigned.
However, the software always assigns P1-P4 to players when using 4-player formats, and always says that one player "Has play order choice" in head-to-head formats.
I've played in a major tournament where the top qualifiers were forced to play as P1 in every game of group elimination finals, due to TDs blindly following Match Play.
Also, the "balanced" option, when used in the group match play format with multiple games per round, gives the same player order for every game in a round. Is this a bug?
