After Feeling Possible Separation of Real-Time double, should I...

When performing an exit-technique, and I feel the projection may have been successful but I'm not 100% certain, should I continue trying an exit technique or should I prepare for reintegration?

If you have separated you would feel it, i.e. you would have moved out of your body. If you're not sure, try to get away from your body. I imagine you don't know because you can't see. Getting away from your body takes care of this.

reintegration is not what you want , the minute you are reminded of your physical body you are attracted towards it to imbibe back into it.
