I thought it would be great to get the confidence interval, but instead it
gives me a "confidence level" that doesn't even make sense, and the manual
does not discuss what the "confidence level" is. Frankly the number is
far too small in relation to the mean and the standard deviation to appear
to make sense.

I want to know the level one can have 95% confidence of achieving.
That's the only confidence level that has any meaning to me. That figure
would have to be a couple of standard deviations above 617,000, it seems
to me. Not, 78,026. Since the SD is 201,000, what does the number
78,026 even mean?

What exactly is Excel's "confidence level"?
