c(t) = log (Price)
m(t) = log (Money Supply)
M(t) - long term trend line of Money Supply

m(t) ASCENDING when dm/dt-dM/dt>0, DESCENDING when dm/dt-dM/dt<0. NEUTRAL when dm/dt-dM/dt=0

G(t) called ASCENDING when 1840 < t modulo 55 < 1864.

m&G are in phase when they are both ascending or descending or m is neutral.

c(t) and G(t) are congruent when m & g are in phase
(dc/dt=dG/dt)
c(t) and m(t) congruent when m & g are out of phase
(dc/dt = dm/dt)

dG/dt > 0 and dm/dt > dM/dt then dc/dt = dG/dt
dG/dt > 0 and dm/dt = dM/dt then dc/dt = dG/dt
dG/dt > 0 and dm/dt < dM/dt then ?

dG/dt = 0 and dm/dt > dM/dt then dc/dt = dG/dt
dG/dt = 0 and dm/dt = dM/dt then dc/dt = dG/dt
dG/dt = 0 and dm/dt < dM/dt then ?

dG/dt < 0 and dm/dt > dM/dt then dc/dt = F(f) dm/dt
dG/dt < 0 and dm/dt = dM/dt then dc/dt = dG/dt
dG/dt < 0 and dm/dt < dM/dt then dc/dt = dG/dt
