I always remember what I was taught many years ago, in connection with
visual double star observing, although it applies equally well to visual
variable observing: 

 That "good" observation which you made is never as good as you thought it
was, and similarly, that "bad" observation which you thought of discarding 
is never as bad as you thought it was. 

Therefore: Always report what you see. Never forestall the later
evaluation.
