Oh Gedman, Gedman, Gedman,
I am so disappointed... You asked about
how to measure leakage and you didn't cotact me?! Puhleeze! I am a leakage measuring expert!
For 2 years I weighed my pads on a Mettler laboratory scale down to 0.01 gram and plotted the results. The curves were further processed to include two and three day running averages, forecasting, and polynomial and logarithmic curve fits.
After my sling surgery in the peak of winter, I discovered that I could be leaking but the pee would evaporate from the pads. I call that "Sub-observable leakage". To determine the SOL level I started noting the relative humidity while running experiments with impervious layers over the pads. I won't bore you with the methods and data but here are the results:
In a dry climate, in the dead of winter, I evaporated about
8 ml/ day when fully dressed and wearing jeans. That means I could leak a full 8 ml about
120-150 drops throughout the day and still be totally dry. In more humid conditions the leak appears to increase but that is due to a decrease in evaporation rate.
I performed a brief confirmation experiment at Cajun style GFMPH this past weekend. I went from a climate with low indoor humidity to a climate with a relative humidity of (est.) 200% and I noticed my pad had drops in it and needed to be changed. I was unable to take hard data. (For all their hospitality Cajun Jeff and Pat do not keep a calibrated Mettler laboratory scale in their kitchen.
Other variables prevented this from being a true test. I was laughing a lot. I consumed a moderate amount of alcohol, and drank plenty of other beverages. I had spicy food that caused me to sweat in places that have not seen sweat in ages. All can have an effect on leakage and thus confound the SOL determination.
Go without a pee pad but have an extra pair of undies in your desk drawer.
Congrats on your fast recovery!
