  We study the photometric behavior of the recurrent nova RS Oph by 58
monitoring light curves (LCs), taken by 5 telescopes. All LCs show repeating
time structures with some quasi-periods (QPs) in time scales from minutes to
hours. In our previous work 97 QPs were detected in the LCs by local minimums
of structure functions and local maximums of auto-correlation functions. The
distribution of the QPs shows modes at 8, 13, 21, 30, 48 and 73 min, where the
mode at 8 min is poorly unveiled. These modes follow a power function with base
$1.55\approx 3/2$ with standard deviation 4.7%. This function predicts modes
also at 5.3 and 3.5 min, which are not detected in the full MLCs. In the
present work we analyze simple small parts from high resolution LCs. We confirm
the QPs modes at 8.0, 5.3 and 3.5 min. Generally, we found 8 QP modes with
regular logarithmic distribution in the time interval 3.5-73 min. We also show
typical intra-night evolutions of QP modes in the minute scale -- sharp or
gradual transitions from one QP mode to other. In the end we find that the
parts of the LCs carry out the properties of the whole LCs at short time scale.
This lead to two well pronounces dependences - between the range deviation and
standard deviation of the LC, as well as between the quasi-period and the
relevant level of the density function of the LC.
