its very clear that GDP has made everyone develop their teams so that they are able to perform well in more than one offensively
I wouldn't say very clear, but certainly a noticable difference.
With regards to your original question, im sure I have seen it asked and discussed before - ill keep searching and I can't confirm anything, but I think th advantage of correctly guessing is the same for both.
However the penalty vs gain argument is an interesting one, and I haven't thought that through or seen any discussion on that. Its interesting.
If I use some random numbers:
Gain of Guessing pace = 10%
Gain of guessing the focus = 10%
Total Gain if guessing both = 20%
Incorrect guesses = %5
Total for both incorrect = 10%
So technically speaking, you could have a gamble, and if you put down a guess both, and only get one right, your net gain will still be a positive 5%. Id be interested to see if this is indeed the reality.
