It all depends on your needs. Calculate the maximum total gpm you'll
need: how many showers, garden hoses, washing machines, etc. do you plan
on using all at once? Remember, most shower heads these days have flow
restrictors and are, what, about 2-3 gpm? Certainly no more than 5 gpm.
That means two people can easily shower at once with 13 gpm. Also, your
system will undoubtedly have a pressure reservoir of some sort that will
fill in the short-term needs (as when someon flushes while you're in the
shower :-)

True, you can't get more than the maximum pump capacity!

I'm no expert, but it could mean that the constant flow of your test cut
channels in the water table (i.e., in the soil), which reduced the
restriction on the flow. Think of it this way: Put a sponge in a bowl of
water. Shove a straw into the sponge and try to suck out the water. Now
cut a hole in the sponge and put the straw in that; I suspect you'll
find it's now easier to suck water through the straw. If you got dirty
water at the beginning of the test, that's what happened -- that dirt
was the "sponge" that you've now cut away from around the well. But
that's just speculation on my part based on what little I learned when
we put in our well.
