It seems to me that the 2 minutes penalty is extreme severe.
I dont like the change of rules after the start, but in this case we will get the final points of first puzzle just tomorrow evening. (GMT)
I suggest a 20-30% penalty instead of the fix 2 minutes. I think it would be more correct.
(And in this case I think it is better, if the penalties are added and not multiplied. For instanse 2 mistake is 40% (x1,4) instead of 44% (x1,2x1,2) )
