What happens if you apply for PR on 85 but it may in process gets down to 80

Just wanted to know if someone has experience with this, in case I apply for PR on 85 HSP pts (when on Engineer / humanities visa), but with some papers that has unclear info, however that info is irrelevant and worst case scenario it will be -5pts and the whole total of points gets down to 80,

Will that turn into rejection or approval still?
