    The installer left a product guide, a technical specification, and the installation manual, but none of them have the cfm/static/wattage chart that you apparently have for yours. The best I could find (and it's also in your link) is a cfm/btu/temp rise chart, which I will also plan to use to get some indication of cfm delivered.

    Attached is a spec sheet from the Goodman website. It may have the data you are looking for. Not sure if it is your model but the site has similar sheets for other models. Link is below.
    Thanks for looking this up for me Key, I appreciate it!

    Interesting... the static for the upper two values are very close to what I measured (probably within my measurement accuracy):

    1600- 0.90"
    1800- 0.95"
    2000- 1.05"

    So that suggests that the delivered CFM is very close to the setting, right?

    I wonder why the 1600 cfm static is so far off?

    Certain fitting designs can through it off.

    Some become more restrictive at higher CFM then others.

    How many times must one fix something before it is fixed?

    Attached is the table I referenced for my Trane XV95 100k btu unit & 4 ton XL15i AC. It has the data for CFMs, static, wattage, and temp rise.

    Thanks Key.. I don't have a similar table for my Goodman, so I will try the temp rise/cfm approach and see what I can see .
