**Science / Tides and Currents / R2:** Smaller solar elliptic constituent. This constituent, with T2, modulates the amplitude and frequency of S2 for the effect of variation in the Earth's orbital speed due to its elliptical orbit. Speed = 2T + h – p1 = 30.041,066,7° per solar hour.

Business / Finance / Portfolio R2: Used in the context of general equities. Number between 0 and 1 that measures the strength of correlation of movement between the portfolio/stock and the index. Indeed, the R2 is the square of the cor MORE
