I actually just finished reading CASA's Flight Instructor Manual on Low Level Flying and it looks like you've got it well covered in your article. I've copied and pasted a minor point mentioned in the FIM, though, .. don't know whether you'd like to include it under the "flying technique" part of your article?
At low level, log keeping is restricted to fewer entries because of aeroplane handling considerations, and at times it may not be possible with safety to make log entries.
