In his 1978 book, New Concepts in Technical Trading Systems, Welles
Wilder does not apply any kind of a moving average to his RSI. In his
example he uses a 14 day RSI.

I hope this helps.

The hybrid exponential average is used in the internal calculation of the Up
and Down sums used to calculate the RSI as documented in the above book page
..
Due to the initialisation process of the xaverage (that is correct in
TradeStation, unlike reported by Phil York in the Omega Bug doc), the RSI
takes some dozens bars to stabilize...as with any recursive calculation
