GCP file bad?

Hello all and merry christmas.

I am having problems with a dataset and can not understand why. I have had some problems with GCP files in the past so I would like a another couple of eyes to have a look at my file.

19 different GCPs with 5 different images attached to each GCP.

Please let me know if somethings not correct.

I’ve not yet used GCP’s myself, but have you tried reducing the precision? 4dp for an easting or northing seems a bit optimistic!
