Phase II wasn't supposed to happen. Phase III (originally Phase II) came from an entirely different set of data. The current Phase II was designed as an error check on Phase I but developed into a phase of its own. It has now provided a backup for Phase I. Through a lot of creativity, inventiveness, ingenuity and brute force I think recovery is complete. There was a lot of work involved - I haven't left home except to pick up mail for the last few days.
Additional changes were made to certain files to ease recovery should the same set of circumstances reappear.
I'm now at the point where appearance of website pages is an issue now under discussion. That's a good thing, since that will be the last part of each and every phase. Progress is being made.
When everything is under control I'm going to work on an analysis spreadsheet for a friend - should be interesting, and a break from what I'm doing.
