Is this actually a mappable event? (Some movements/billets aren't really points; some are.)
Most of it is very mappable. Especially if we map the events to the units location ie we know where the unit was, so you are already near it, use the gsgs base maps to find the location, and then use the grid reference to find the exact location. Very very useful

Does the location text contain enough information to geocode? (Grid refs are gold; "Hinkelenoord" alone is harder.)
Grids are perfect. Locations are harder, but I think over time as we map a place with a name, it needs to be captured into like a gazetter or toponomy record so that we can find it again. I think the more we do this, the better we will get at geocoding these locations. We will also get better at recognizing when a location is not specific enough to geocode, and when we need to do some additional research to find out where it is.

Would Jonesy accept it without changes, edit it, or reject it? Estimate the proportions.
I think Jonesy would accept most of it without changes, but there would be some edits for clarity and to make sure that we are not including any information that is not supported by the war diary. I would estimate that about 80% of the events would be accepted without changes, about 15% would be edited for clarity or to remove unsupported information, and about 5% would be rejected because they are not supported by the war diary or because they are not mappable.
