If every single slab of tactile paving has been done wrong (which judging by the reporting on here it definitely feels like) then there is a higher order flaw in the spec as arellcat says. The person laying the paving consistently interprets the spec wrongly then there is something wrong with the spec.
However, just to contradict myself I was in high morningside last week and had to head to Waverley. This was in the middle of the day. I found myself on what I can only assume was the quality bike corridor? However, my experience was very positive. Only a single salient exemplar at wrong time of day and all lights may have been green but I sailed from a point well beyond the bike station all the way to Top of buccleuch St before turning right just before the mosque and then down towards the cycle service. I was in a lane that was out from the car parking but not hampered by cars that were being driven. It flowed well, the surface was smooth and clearly delineated. Obviously, might be much worse in rush hour.
The contractors should learn by doing. But maybe the opinions on what is right are not consistent? Personally I think the tactiles parallel to the direction I am going are wrong as they are slippy when wet. I cross to the perpendicular side if no peds about. If peds about I really slow down, which would seem like the intention of the installation (apart from helping the non existent visually impaired, they do exist but just not around any tactile paving slabs I have ever seen). Other objections such as width of ridges and the middle strip do of course exist.
It would be good if these details were correct. It is nevertheless even better cycling around Edinburgh at the moment with the meadows Tarmac new, the strath earn road top of marchmont Tarmac nice. The lovely Tarmac from Baird drive to stenhouse beside the tram a joy etc. even the stretches that have had temporary fixes are less bumpy at the moment - quite a few bits of my commute have the wrong filler at the moment. It will all go to pot in the winter so I see the argument for doing it right but at this moment my experience of cycling in Edinburgh is the best it has ever been. Even leith walk, full of pavement parkers or cars abandoned in the middle of the road has a nice new surface.
