A DCF doesn't require use of a spreadsheet. It also doesn't require complex assumptions.
Buffett does the DCF in his head. A unit economics analysis is a DCF done bottoms up . LTV/CBCV can also be calculated in someone's head or roughly "eyeballed" based on pattern recognition.

When we put a high multiple to sales, the most important thing to worry about is - what could disrupt those cash flows. A lower multiple to sales (like a 1x or 2x) justifies Yo-Yo cyclicality and 10x sales implies relatively stable gross margins, cash flow and business economics.
