Hi John, a quick followup and thanks for bringing this up. I added an Issue
for the developers to look at re marking tiles with Cloud Cover in GitHub
and added the following in the instructions for the Task #777

*Note: These tiles are relatively large as it is a large area to cover.
please feel free to split the tiles as you see fit. *
*If the tile is partially obscured in cloud we suggest you split the tile
 and map what you can. If there is a significant amount of cloud cover, we
recommend that you leave the large tile as it is and map around the cloud*


Best Regards

Mark Cupitt
