I used PhotoReading back in graduate school to help me with my studies in physics and mathematics and did not find significant improvement in my memorization of tables. It did speed my comprehension of the math and physics, but more in the realm of how to problem solve and how to understand the theory. Anyways, except for a few commonly used logarithms and sine/cosine values, why would you want to memorize them? Most of mathematics and physics is done analytically, with values substituted back in at the end.
