Dear Mr Sakai I believe that in an effort to fit the project plan on a single sheet John reduced the overall scale considerably. This has meant that the timelines are not single weeks but multiple weeks. The second line of figures are dates, every 2 weeks it would seem, which fall within the timescale indicated by the top row of numbers. Usually on the full scale project plan these would be individual days. I hope that makes sense, we could send out the multi sheet version, with actual weeks and days if it would be clearer. Regards Amanda
