Superintelligence would be both more complex and subtle than the suggested abilities you have given your person with a giant mind. In fact, total recall is a handicap rather than an asset. There is a famous study of a Russian afflicted with a total recall memory. if I find it I will add in an edit. As for being a super-calculator, again that doesn't very much at all. Even WWII mechanical calculators could do as well. He could get a job as a computer with that calculating skill. A computer in WWII was a person who did the long, laborious calculations associated with scientific research or actuarial tables. This sounds more like an idiot savant than an intellectual superman.
As for the power of making deductions, again this is overrated. Deductions are often a poor way of thinking through problems. Sherlock had his Doctor Watson, but more importantly he had his author, Sir Arthur Conan Doyle, on this side to ensure everything came out right.
If you want to construct a superintelligent person, consider the full gamut of intellectual and cultural skills where learning and problem solving are at their highest. The capacity for languages, mathematical skills, the sciences, linguistic skills in writing and talking, the ability to persuade people, to tell jokes, a deep psychological understanding of people, and strategic planning (by this I don't mean simply military tactics, but the ability to plan how complex activities or organisations can be done or run). Foremost among the abilities and skills of any superintelligent person would be his ability to learn anything and everything extremely fast.
He will have a habit of coming up with totally unexpected solutions to problems. This will be due to his superlative level of creativity.
It is an open question whether his superintelligence would extend to controlling and facilitating his motor skills because if it did he would be the best athlete or sportsman in the world.
Also, if he's really smart, he will have learned long ago how to conceal his superintelligence, and to blend in with normal human beings.
