I realise that paper tables and graphs will soon run out of space so I wondered about a spreadsheet version and graph. Unfortunately whilst I am very much at home with CAD and Graphics applications I am not very good with spreadsheets beyond normal stuff.
This is my attempt. Maybe some one can do a template that we could attach to each valve and fill it in as it goes on its travels?
