Subject A is a 25 year-old male of average height, average build, and average fitness.
He started at 35 ESP, 35 Occult, and 35 Humanities.
The test began with 10 attempts to self focus. Then he removed all ESP skills and reset Humanities to 35, followed by another round of 10 self focus attempts. Finally, all Occult was removed, Humanities reset to 35, and 10 final self focus attempts were made.

I insisted on the removal of all learned Humanities skills to validate the test by removing that additional knowledge as a factor, maintaining it as a control.

I didn't have her forget any Humanities, since she was maxed out it was a constant already.

I decided to step down the elimination gradualy, to see if I could keep some ability to focus (weapon) while raising my RT reduction abilities.

I'm forced to admit that I've been a bit lax regarding mental training, my humanities is only intermediate, and my ESP is basic at around 100 (that one I deliberately kept lower, really only use telepathy and infravision, with just the occasional blast for fun). To make numbers easier, I did all my testing in the Van Gogh studio, painting watercolors.

Knowledge of the Occult appears to have a definate negative effect on Humanities skills.

ESP ability is the far more dammaging of the two, as evidenced by the ability of the Subject A to begin successfully focusing with Occult and no ESP, but for Subject B to fail with no Occult and some ESP.

The most telling evidence was Subject D, who exhibited a dramatic loss of focusing effectiveness with 500 Humanities and 0 ESP.

Unfortunately, when I applied these results to myself I did not gain any extra measure of time, but I believe this was largely to do with my neglected Humanities and high (for someone who wants to focus) ESP Ability.
