For my model I have constants to be applied such as projected inflation rate, depreciation years, and other values to be set by users as what-if options. There are too many variations the users want to create disconnected tables - e.g. listing every inflation rate by hundredths of a percent - resulting in huge lookup tables for 12-15 constants, so it's simpler to have a default table with values for each constant that I import into the model with Power Query.

Once the table is loaded however, I'm sure there must be a simpler way than I use to extract the value the user has entered so I can use it in calculations... I essentially do
Code:
Inflation Rate:= CALCULATE(MAX(DefaultTable[Value]), DefaultTable[Lookup] = "Inflation Rate")
then I can use the measure [Inflation Rate] in later formulas. This seems so convoluted that I'm hoping there's something blindingly obvious that I've missed.

How to total the visible cells?
From the first blank cell below a filtered data set, press Alt+=. Instead of SUM, you will get SUBTOTAL(9,)
I note that you're not using ALL? Try the general idea below:
<code style="background-color: rgb(239, 240, 241); border-bottom-color: rgb(36, 39, 41); border-bottom-style: none; border-bottom-width: 0px; border-image-outset: 0; border-image-repeat: stretch; border-image-slice: 100%; border-image-source: none; border-image-width: 1; border-left-color: rgb(36, 39, 41); border-left-style: none; border-left-width: 0px; border-right-color: rgb(36, 39, 41); border-right-style: none; border-right-width: 0px; border-top-color: rgb(36, 39, 41); border-top-style: none; border-top-width: 0px; box-sizing: border-box; font-family: Consolas,Menlo,Monaco,Lucida Console,Liberation Mono,DejaVu Sans Mono,Bitstream Vera Sans Mono,Courier New,monospace,sans-serif; font-size: 13px; font-size-adjust: none; font-stretch: normal; font-style: normal; font-variant: normal; font-weight: 400; line-height: 16.9px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; vertical-align: baseline; white-space: pre;">SalesMeasure = CALCULATE(SUM(Table1[Sale]), ALL(Table1[User]))
</code>
