I was taught plum and dot at College and as an apprentice I used plum and dot method in kitchens and bathrooms that was going to be fully tiled. We often had to to do the tiling so perfect internal angles was a must.
BG marketed a dot kit for dry lining in the early 80's which was perforated thin board and double headed nails for the string. I used them for the fully tiled dry lined rooms.
We used it at an old Hall in an old barn which was being converted into an electric station. All the walls needed to be a within a millimetre but they were like a snakes belly!! 3 days dubbing out and it was done. plumb and dot came in handy on that one.
Many years ago id use strips of 9.5 plasterboard where walls were desperate, all the old uns would take the piss but it worked a treat.
Even used that method with timber to level screed when first starting. Got the proper result.
