You seem to be very enthusiastic in usage of superlatives in this thread. Let me slightly dampen your enthusiasm with the help of the following anecdote. In contract bridge (a game played with cards) it is usual for one team to sacrifice and try to come up with better than a par score. But sometimes the sacrifice turns out to be phantom in the sense that the opponents do not have a good hand and the contract would have failed in normal play. The upshot of all these is that when the opponents double a sacrifice contract they lose a bundle of points for the under-tricks. Once when a team went down and conceded a bundle of points (the scoring is somewhat complicated to be described to a lay person) he asked his partner how many points they have lost in that particular hand. His partner came out with the reply of 2300 in no time. The questioner was impressed with the speed of answer and said that he must be a mathematical whiz kid to come out with such a quick answer. His partner replied with a dead pan face "No... Just practice"...
