About Potential IQ gauged, Potential IQ and other scores, you need read these articles (writed in Portuguese):

I will try to do a summarized explanation on the difference:

Non-gauged Potential IQ is the best score to determine the antlog of ratio of mental potential. For instance: 10 people, each of them with potential IQ 100, works in synergy, have potential of intellectual production similar to 1 person with potential IQ about 126. That not have any relationship with rarity IQ, that is based on normalized scores, i.e. if 84% of people obtained raw score 5 or lower, then score 5 is equivalent to rarity IQ 116 (average + 1 standard-deviation, i.e. 100+16). If 98% of people obtained raw score 13 or lower, then score 13 is equivalent to rarity IQ 132 (average + 2 standard-deviation, i.e. 100+32). If 99.9% of people obtained raw score 21 or lower, then score 21 is equivalent to rarity IQ 148 (average + 3 standard-deviation, i.e. 100+48). Etc.

The uncertainty in scores is asymmetrical, for that an gauged IQ 160 can have 70% of probability to stay between 150 and 161 or can have 70% of probability to stay between 159 and 170. To minimize the distortion, the gauged IQ subtract 1 standard deviation and add 1 standard deviation. In this example, the first case would be about 155 and second case about 165. This problem occurs when anybody make few points in easy questions and a lot of points in difficult questions.

Sigma Test for prospective members
Merci à Philippe Jacqueroux pour envoyer ce beau puzzle!

Very nice, difficult and interesting

Este é um teste gratuito, constituído por uma única questão, que é aceito para admissão como “prospective member” em Sigma Society IV, III e II. Um prospective member desfruta os mesmos direitos dos full members. A única diferença é que consta no certificado de filiação que se trata “prospective member”. Após um ano de participação em Sigma, com base em sua atividade no grupo, pode passar ao status de “full member” em um ou mais segmentos. Além disso, se em qualquer momento for aprovado em algum dos critérios aceitos para admissão plena, também passará imediatamente a “full member” nos segmentos correspondentes aos critérios atendidos.

Frequency distribution of rarity IQ

Frequency distribution of potential IQ

Some psychometrical properties of the Sigma Test, based on 152 testees:

The people are accustomed to the norm system based in rarity and they ask me a lot of times: "Is rarity 1/32,000 equal to 4 standard-deviation above average?" And the only answer is: "No. Rarity 1/32,000 cannot be calculated with safety, because in this level, the function that represents the distribution of IQs is completely deteriorate and doesn't make sense to speak in rarity. But if it was possible speak in rarity, maybe it would be equivalent the approximately 5 standard-deviation above average, for any test correctly gauged." To understand better, see the example of Chess games, with base in 2,600,000 games from Mega Database 2004: the average is 38 moves per game with standard-deviation 16. Is the rarity 1/1,000,000 equal the how many standard-deviation above average? Theoretically it would be +4.75sd, but in the true is more than +9.5sd (more than 190 moves), and the function doesn't behave as a gaussian out of the interval -2sd and +2sd. For that the correct way to measure the intelligence cannot be by rarity. The correct way has to be by ratio of potential. Besides, a proportion scale provides much more useful information than an approximately interval scale, with distortions and with arbitrary zero. The rarity scale is satisfactory exclusively for interval between -2sd and +2sd. The Sigma Test certificate also informs rarity IQ because practically all of high QI societies use criteria based on this score, but this is an information without meaning.

Scale type: ratio (antilog of potential IQ). This is the pioneer test in the world to use a coherent ratio scale. See more details in the texts on the norms sep. 2003 and oct. 2004.
