  We consider several factors concerning the design of observing strategies in
Cosmic Microwave Background (CMB) anisotropy experiments. First we consider the
number of independent points on the sky one should observe given a fixed
observing time. Given an assumed level of sky temperature fluctuations,
$\sigma_{sky}$ and the presence of instrumental noise $s$ in units of K
s$^{-1/2}$ and a total observing time $t_{obs}$, we find there is an optimum
number of points in the sky to maximize the confidence level of a detection.
This number is a function of the signal to noise ratio $R^2 = \sigma_{sky}^2
t_{obs}/s^2$. We verify this analytical result with a monte carlo simulation,
which also includes the correlation between different positions in the sky.
Furthermore, using an $n=1$ spectrum of Gaussian fluctuations, we show that
arranging the observing patterns along a (great) circle, a raster scan, or a
randomized pattern yields results which are indistinguishable in Monte carlos.
