OpenStreetMap
I had the opportunity to fill in a few gaps on my way to and from a meeting in Creiff. So I have added the road to Huntingtower, a few missing roads between Crieff and Madderty/Almondbank, and on the way home added a minor road at Rumbling Bridge, and one near Coupar Angus (which completes the normal roads in that block.)
The rumbling Bridge road overlays a poorly drawn fragment of highway, incorrectly labelled as tertiary. There is so little congruence that I cannot decide what to do with the existing fragment as it links at both ends and I can't determine from the GPS the position of the links on the trace I made.

There seems to be a fair bit of low-quality tracing from out-of-copyright maps in Perthshire, often with an unwarranted highway=tertiary. I'd suggest you're bold in deleting anything that you don't think is good enough.
Some of the more recent OOC background tiles are significantly better than the early ones, and can be of use in restoring the connections - especially if you've got a GPS trace to align them to.

Where I am happy that my GPS trace is good then I am quite ruthless. In this case though there were some connections that needed to be sorted and I hadn't logged those. The original author did the final edit and we are both happy that it is the best accuracy that can be obtained at this point in time.
There are a lot of mis-annotated unclassified->tertiary roads though.
