Planets Conjunct the DC or other Angles

I was just wondering when reading a synastry chart if a planet that falls within a reasonable orb before the Descendant still counts as being conjunct the angle? Does the "planet" person still affect the "angle" person the same way as it would if it were exactly conjunct or falling after the angle? Just wondering how it's interpreted by everyone.

If the planet is heading towards the angle then I count it as being impacted by that angle. And in synastry I have found the angles to be very important.
