The afflictions to strong planets are effective only if they are within one-degree longitudinal range.  The afflictions to weak planets are fully effective if they are within one-degree longitudinal range.  Afflictions are 80%, 60%, 40%, 20% and 0% if the afflicting planet is having 1 degree, 2 degree, 3 degree, 4 degree and 5 degree of longitudinal difference, respectively, from the weak planet. It is most severe if the weak and afflicted planets are badly placed.  The experience based on the feedback of the people  indicates that these afflictions can be  taken care up to 80 - 90% with the help of the astral remedies, i.e. wearing of a Kavach, and performance of charities, etc.  If the lord is strong, the damage is minimum.  For non-mooltrikona signs the impact of the affliction is 100% to 0% depending upon the longitudinal difference between the MEP and the afflicting planet as explained above for the planets.   If a planet being lord of a house is weak, one should see the strength of the significator (karaka) and the supplementary houses.
