Answer, 2<6, Crew B is faster.
Comparisons, A+
Congrats, unless you used your fingers to see which was more.

Next question: what is 6+2?
And what could (6+2)/2 mean?

Watch out for the noise that cheap gens make. A lot of folks say it doesn't matter since it is just a backup but during an outage walk around and listen. Some of them are so loud they would be hard to tolerate even running intermittently. Depending on your proximity the neighbors might not be too happy either. More to the equation than cents per KW.

In the fall I may buy the thing.

Just more irrelevant numbers. Why do you think they would mean anything?

Why does one care about the average of the two crew times when comparing the two crews performance?

I get a catalog that had one of these air-powered horns that use a canister. It said: 120 dB at 10' and works up to a half mile.

Using a 6 dB reduction for each doubling of distance this works out to something like 70 dB at a half mile, so if you build a doghouse around this thing with a box fan for cooling you may be able to get it down to this level, which I assume is background level for some environments.

I'll assume your motives for asking questions are different from Mr. Port.

You might try searching on

"management science"
"quality control"
ANOVA
quartiles
"standard deviation"
"normal distribution"

Computing averages are the first baby steps for evaluating performance.

How many kw does it put out?
Hard start kits installed in your ACs?

It seems with 5kw you can't do it all and with 20 kw you hardly ever run it to full capacity.
