Does 80% C and 20% S sound most accurate?

Many TSP investors wish to use the C and S funds to replicate the Total Stock Market. You can hold the C Fund (tracks the S&P 500) and S Fund (tracks the Dow Jones U.S. Completion Total Stock Market (TSM) Index) in a 5-to-1 ratio to approximate the total stock market. According to the TSP, "As of December 31, 2020, [...] the Dow Jones U.S. Completion TSM Index made up approximately 18% of the market value of the U.S. stock markets; the S&P 500 accounted for the other 82%. Thus, the combined S Fund and C Fund cover virtually all U.S. stocks."[5]
Using 5:1 as described would lead to 83% C fund and 17% S fund.
