Well at the end of my 4 days what is the conclusion?
Good news: Job done. Script finished. Just rewriting to go now!!!
Bad news: Crazy time management. I believed that just chunking through the script would be enough. So by the time I'd written my days allocation I just kind of stopped work and started browsing etc. I need a kind of triple days target. One phone call, one gravity activity and the page count. Then I can slope off.
Conclusion: Beef found - more cows in field.
