The current rule doesn't even make much sense!
The player who reaches the finish with less turns wins. In 2v2 and 3v3 the team that players reach the finish with less turns combined wins. Remaining turn time is a tie-breaker.
If you plop, then use teleport to place where you started the last turn.
It's the same with TTRR, it's illogical. Sometimes the loser is the winner in TTRR because you don't use milliseconds.
Honestly, who makes up these rules? Are they on drugs? Did you let children under 10 years of age decide?
It's pretty simple.
For TTRR - Start using milliseconds. It doesn't matter if you like it or not, it literally represents the truth and you're all liars for avoiding that all these years. I've found multiple replays in the past where the player who actually won, went on to lose because of this illogical rule.
For Big RR ideally it would be who reaches the finish in the least amount of time, but people are too lazy for that, but you could EASILY make it better:
"The player who reaches the finish with less turns wins, if they finish during the same turn then whoever had the most turntime remaining wins.
In 2v2 and 3v3 the team that finishes both turns first with less combined turns wins. If both teams finish on the same turn then whichever team had the most combined turntime left wins."
Really, it's not rocket science for crying out loud. I've been saying this for YEARS but you still prefer to play with a false reality instead.
Ideally, we would be completely changing the Big RR scheme because 40s turns is rubbish, I'd rather TT Big RR, it's much more accurate and balanced.
But again, people like to torture themselves with illogical schemes.
