I recall a conversation you had with #[2] on #[3] 2 years ago where you discussed the challenge of interpreting S2F as it approaches infinity. Is there value in inverting this to so that it decays to zero ("F2S")?

Comparing this "F2S" number for various indices with respect to each other (i.e. USD, BTC, Gold, Real Estate...) might reveal a "winner" for base unit of account and there may be some minimum value at which one unit overtakes another as the base.
