Editing ALGORITHM II (section)

=== '''Step X. Search for Preceding Models''' ===

The program identifies all possible models in accordance with Algorithm I, starting from the initial point of the preceding trend or starting from the presumed initial point of the preceding trend, see step 1.3.).
In these models, the actual t.6 is determined, and if there was no intersection of TL, the Presumed t.6 (P6supp) is used. The algorithm for finding the actual/presumed t.6 is described in the branch of Algorithm I, see substep 5.3.

Models on the preceding trend, with TL coinciding with t.3 of the EAM, are (directly) preceding for the given TL.

Models on the preceding trend, for which the following conditions are simultaneously satisfied:
: - actual/presumed t.6 precedes or equals t.3 of the EAM;
: - t.6 is aligned with t.4 of the EAM;
: - the level of t.6 lies between the levels of t.3 and t.4 of the EAM;
are considered preceding corrective for the given EAM.

From models with the same t.4 and the same t.1, the model with the later t.1 is selected as the priority for choosing t.2.

From the remaining models with the same t.4, only the very last model is considered as both preceding and preceding corrective (i.e., with a later t.5 or without t.5) – one of each type.

If there are more than 10 preceding and preceding corrective models (rarely encountered), only the last ones are selected (the last ones are determined as those with t.4 lying later than others).
