I drive a Bolt now. I average about 4.6 miles per kwh and I've traveled
about 4,200 miles since the end of December or 600 miles per month or 20
miles per day. I'm retired. This means I have to save about 4.3 kwh using
LED bulbs over incandescent bulbs on a daily basis. Each bulb, if it
replaced

I acknowledged that twice already.

Correct.
What it says is that 10 different things they did break out, and the
total power used, follows a n

Excuse me, i think Bob said 50 lights, 5h, 75w so that is in the order of
20kWh, not 150.
So it is maybe twice as much as avg, not 10x.
With the 15+ kWh Bob can save with LEDs, he can drive approx 50-60 miles a
day.
BTW, Lee, you are not alone. My daily commute is 35 mi round trip.

Well you're wrong.
The graph is smooth and continuous.

That's exactly what standard deviation is for, to know the probability
(or occurrence) of a given situation. A broadly spread dataset is

The calculation was for 50 bulbs 5 hours a day. In my house, I leave 3
basement lights, and one shop light on all the time (hard to get to the
switches). And outdoors, there are 4 lights on dawn-to dusk (say 10
hours).
So, do the math. The 4 bulbs on 24/7 are the same as 19 bulbs for 5 h
ours.

Which is some extreme outlier family who's electrical usage is
literally 10x the average home.

I don't know about his interior lights, but my neighbor has several lights
in his carport that are on 24 hours per day.

The average house with compulsive behaviors who turn off every unused
light will be 10% of this as Matt note
To make the math work, I should have said, "the average house with
teenagers leaving all the lights on for 5 hours a day". [50 lights times
60W saved times 5 hours a day = 40 miles daily EV charging]
