The ability to use decimal scores like 1,5 or 11,3 usefull for automotive events and races.
Promising at first but had to abandon the use of challonge brackets because it will not accept decimal scores - This was to be a chess engine tournament and draws are inevitable. I tried a test run and could not enter 0.5 - 0.5 as a result. Just came back 0 - 0. Therefore, totally useless to me.
We use half points in our billiards league as well and currently cannot enter them. :( If it's a matter of not wanting all of the brackets to have decimal scores - then make it a choice on the settings whether to accept partial points or not.
