You are welcome to split the tasks as you see fit to suit you mapping
style. It is always a trade-off with larger area sizes, lots of cloud
cover. Smaller tiles results in lots of un-mappable tiles covered in Cloud
that people leave untouched and so on. I think splitting them is the way to
go, pick the ones that are clear, and leave the tiles with lots of cloud
cover un-split so they can have some mapping and be marked as complete.
Does raise an interesting thought for followup mapping, in TM, should we be
bale to mark a tile as covered in cloud, un-mappable so it can be redone
later when new imagery is available. Hmm, will log an issue on TM for this
