That seriously does not make any sense to me at all the "maciej" way.
Considering no one starts on the word "Start" they place on the line where "Start" is, it should be the same for "Finish" surely???
Anyway, it doesn't really matter, as long as the players are fine with it, if you check all my RR's so far in TuS, everyone just finished on the line, not the word.
Seriously, you don't touch "Start" so why touch "Finish"
And if this is the case, 1 of my rr's, I would have actually won, or at least drew if you must touch finish.
