well I tied the pencil mod, and I guess I'm either missing something or did not do it right, because my resistance did not go down at all, no matter how much I did it or how carefully or anything. Resistance was at like 760 no matter what I did. At one point it went down to like 730, and then after a few more strokes, it went up to 760. wtf?? I'm supposed to be penciling the middle of the resistor, right? In between the two points that you touch with the MM? I tired doing light strokes, I tried doing rough strokes, it did not do anything. I dunno. The fact that I have to take my card again and reapply TIM each time is a PITA as well.
