Short-term Timing Component of I1

One of the components of I1 is a solar-lunar model (the only non-environmental component).  I have found that this component, when used with I1, helps me to pinpoint turn dates remarkably well.  Some historical charts followed by a rule set:

The rule set for the short-term timing component is as follows:
If a peak is below 10.5 then sell the peak
If a peak is above 10.5 then sell the return to below 10.5
If a trough is above +2 then buy the trough
If a trough is below +2 then buy the return to above +2
