Line 45:
: Flag as unstable if the max value is outside of the time series by '''<tt>TOLERANCE</tt>''' (outside means either not close to any of the data points or an interpolated value if the time of max falls inbetween data points)<br>
* Detailed Description Rule 4: Same as rule 3 however with the minimum value rather than the maximum value
* Detailed Description Rule 5: The following rule uses a <tt>'''TOLERANCE'''</tt> defined as
<pre>TOLERANCE = UNSTABLE_PERC_LIMIT multiplied by the time series range (time series max - time series min).</pre>
: This rule also defines a bounce as where there are consecutive gradient sign changes<br>
: e.g.<br>

: The gradient sign change is considered 'consecutive' if it occurs within '''<tt>FORWARD_LOOK_COUNT</tt>''' timesteps<Br>

: The magnitude of a bounce is defined as:<br>
