For completeness, I list the procedural sequence that should be followed with the tables: (repeat for those who are interested, I can send you by email all tables for all relative bearings ad all LOS type)
Scenario: bearing-only TMA, track target with TA, ownship and target(submerged) in search phase.
i) Measure the Br at time 2 and 4. (target range is decreasing or increasing?)
ii) Recognize LOS type. (LAG, LEAD)
iii) Whit the Br measured at time 4 and relative target bearing measured at time 2 --> choose the corresponding table. (RelativeB+LOS+Br --> Table)
iv) Obtained the probable interval target range, seek a possible alignment of the points in the dotstack in the interval range. (Strip plotting)
v) If the probability is friendly, the target will not be far from the solution found

. Otherwise you will fall into the 5% probability that the interval be wrong
