The normal rain fall for the rainiest month (August) in Tampa is 7.6".

No matter if you use which simple arithmetic is used it still takes 3"
of rain in one day, not accounting for rain run-off, splash-off and
wind blow-off and not collected, (or half the rain fall of the
rainiest month of the year) to collect the 2000 gallons claimed, -
which is 1) non-sense and 2) not helpful to anyone thinking about
building a cistern for themselves.

The roof area you mentioned was about 950 ft^2.  Add to that the pool
itself (area 176 ft^2) for a collection surface of 1126 ft2.

2000 gallons is 267 ft^3 of water, divided by the area of collection
works out to almost 3 inches of rain.

If you collected six inches of water in an open bucket placed away from
any structures, you did indeed have six inches of rain (at least in your
general neighborhood).  That's basically what a rain-gauge is.  If the
sides are straight and parallel, the depth is a direct measurement.
Most rain-gauges have tapered sides to make it easier to measure small
amounts, but that doesn't sound like a problem in your case.

Ah, I see. The bucket is tapered. Wide on top, 1/2 the diameter on
bottom. It is a small garbage pail. So I guess I did get 3 inches of
rain that morning. The pool filled up within 3-4 hours.

daestrom,

Valid point, but even adding an extra 167ft2 the pool area collects,
this system only collects 350 gallons on an abnormal .5" daily
rainfall to fill a 2000 gallon deficit, non-sense.

So to get this part of his fairy-tail to come true we need to boost
the rainfall to 3" per day, or almost half of total average monthly
rainfall for the wettest month of the year needs to fall on one day to
make this part of fairy-tail come true. More non-sense.

I currently use only 6K gallons a month of city water. Why is this so
hard for you to accept? I only plan to use the collected water to wash
clothes, flush the toilets, and maybe wash the cars.
