Seeking Excel equivalent for ER calculators

If you plan a vacation, you might look up the mean low temps and the record low temps for that time. It would be silly to assume that they couldn't also go lower, that's how records become records.

You're looking at the past because you are assuming it's representative of the future. Not that it couldn't be different, but that it's a stand-in.

Just like looking at average and record temps. You look at the average high and low and record high and low and then conclude it tells you nothing about how you plan your future vacation.

Have you tried this one. Helped me at age 79 and Jim is very helpful.
