I agree with you in principle Komo, but this map is pretty hard already so I am ok with the hat thing being allowed. Doesn't seem to happen too often anyway, and when it does it is normally only a 50 or 75. I doubt anyone will get a decent rec here doing it this way.
It's irrelevant if it happens a lot or rarely though, the point is that it happens, and instead of scoring 0, they will score 50+ when they don't deserve it, for me this is just as bad as someone asking for a rethrow because they drilled by accident at the start of their turn, in theory it's all nicey nice to allow someone to take their turn again, but it's a competitive game a turn used should be a turn used, and a miss should be a miss, there should be no room for arguement.
I am not trying to be an asshole here, just trying to keep the scheme strict, professional and more skill based which I have done a great job of so far, if you want to play with luck, then play funners and do whatever you wish...
