Or "riggers tape".
In the military we just called it "green tape" but the NSN was "Waterproof Tape Dark Green, NSN 7510-00-074-5157".
My personal NSN favorite was "Buckle Belt Trouser Black Oxidized Finish, NSN 1095-01-277-1739"

I was looking for an accident report I read years ago where a piece of duct tape used to temporarily patch a hole in the skin on a horizontal stabilizer came loose, started flapping, disturbed the airflow over a trim tab and caused a loss of control. The airspeed when it occurred was about 150 kts with the moral being it really is just 100 mph tape, not 200 mph tape. Sadly I can't find it, but I really don't recommend it at airspeeds over 100 mph.
We used duct tape to patch small holes and tears in fabric to ferry the planes home for permanent repair, but this is the most extreme case of duct tape covering for a ferry flight that I've ever seen:
100mph tape in use
A PA-18-150 with a cargo pod isn't going to go much over 100mph, so it's well suited to duct tape repairs.
I get what you're driving at but it actually is true for the purposes of IQ scores.
I'm not betting most people remember what a median is, but most get what a "mean" is so it's more effective to use to get the point across.
In any event with a normal curve the mean, median and mode will all occupy the same point on the curve, and IQ score and the classification system for IQs are based on the concept of a normal curve. It has to be that way because at best we're just sampling the population, not testing everyone.
Actually the median is the one correct measure of average in the IQ distribution. It's the measure used whenever there are instances that cannot be measured, but is known to be at the high end and/or the low end. These unmeasurable instances can be accounted for in the calculation of the median, but cannot be accounted for in the calculation of the mean. We treat IQ as normally distributed, but there's no good evidence that it's true. We can say that it's normal given the measurable range, which is just fine for anything other than internet forum discussions!
Concerning team thirds, there is a nice one-to-one correspondence between any two diver's tank sizes and psi so that once you determine that your turn pressure is 1800psi and your buddies is 1600psi, then that 200 psi difference is virtually the same across the range of start pressures. Until it gets high or low, which is unlikely anyway. I published this in a table in the UWS based on common tank sizes and posted it here in the forum a few years ago. I'm sure a search would turn it up again. It needs updating what with worthington now in the picture (maybe it was published more than a few years back).

Sooooo, I'm coming up Monday, the 10th, for some diving, need a buddy, who wants to calculate 1/3's in the basin with me???
You're asking the wrong question.
I definitely WANT to, I just can't get there till after christmas... :(
