Injector results?

Freelander td4 runs rough on low idle and has a misfire on low idle. I sent the injectors for a overhaul 2 years ago, just done a leak check and these are the results. These results were after 5 mins on idle.
Would I be right in thinking no.1&4 injectors need overhaul again, to cure the problem?

Do a one or two minutes test then report back they all look like they need sorting out to me. pictures below are 2 minutes, & 4 minutes. on idle, I refurbished them all cleaned the nozzles and fitted new copper washers it ran great after.
