Mike,
I have been telling guys to measure and plot their leak rate since I joined here. I'm glad a professional has made the same recommendation.
I like how you recognized the importance of measuring individual pads since their weight can vary significantly when compared with your low level of leak.
Obviously I had the same problem post sling. I did not like the idea of putting an
open pad on the scale so I weighted all the components of a pad package and discovered that the outer wrapper and paper backing were very consistent. I kept a used wrapper and paper near the scale to act as tare for my pad weight. They weigh 1.1 grams and seldom vary by more than 0.05 gm so the result is quite close. A tolerance of 0.05g is a small price to pay for sanitation. Pads can very by as much as 1.5 grams and we can both agree that is unacceptable. To save time, I would weigh 5-10 pads in one sitting and write the individual weight on the package. By the way, pads are slightly hygroscopic, meaning they absorb water from the air. My scale is so sensitive I can actually measure pad weight gain as a function of relative humidity. Theoretically I can weigh a calibrated pad and tell you the RH. Of course, I can do that now with a $4 device from Garden Factory but it is so much more impressive to use a scale costing 1000 times that. It is also handy for figuring out how much coffee to put in the pot.
You mentioned measuring a cannon ball's flight and I am only slightly embarrassed to admit that, yes, I've done it - only we use potato cannons. I also have a high end chronograph so I can measure the speed of projectiles up to Mach 4 to a resolution better than 1 part in 10,000. It can measure any shape from potato cannon spuds to BBs and speeds from a slow pitch to those well beyond .223 armor piercing ammo.
Your image of the TENS unit is not far off. The incontinence physical therapist I went to made me do it for a while before finally giving up. It sends electrical current to the muscles forcing you to kegel every few seconds for as long as you can stand it. It does build the muscles. Unfortunately in my case that turned out not to be my problem. The 76 micron equivalent hole in my shortened bladder sphincter was the issue. It took the sling to fix it.
It is a pleasure meeting you. If you come to GFMPH here in Sept I'll weigh your pads for you.
Jeff
