Hiya, welcome to OSM and thanks for your contributions around the Wyre area recently :)

If you’re going to focus on improving alignment of things, please make sure the aerial imagery you are using is aligned to a source of ground truth first. Frustratingly, aerial imagery is not guaranteed to be aligned, and its alignment varies over time as it’s updated. It also varies across the country. In some places it can be up to 3m misaligned from (say) a GPS reading, in both directions.

The most convenient way to align the imagery is to turn on the ‘OSMUK Cadastral Parcels’ overlay in the ‘Background Settings’ panel on the right of the editor. It will turn on some thin blue lines which correspond to Land Registry parcels. Adjust the ‘Imagery Offset’ below until those lines consistently line up with obvious boundary features on the aerial imagery, such as fences or road edges. Fence junctions are particularly useful.

For example, around the west of Skippool it looks like the correct alignment offset is 0,-1.49. Note that this will be different in other places.

There’s some more information about it here: https://wiki.openstreetmap.org/wiki/Property_extents_in_the_United_Kingdom — I’m also happy to answer questions you might have about it.

Sorry for the long comment. It seemed to me you were making a lot of alignment improvements, and I thought it would be better to tell you about this slight complication sooner rather than later!

Happy editing :)
