To oppose mhansen and just to show different situation:
Site that haven't been edited since late March:
Example Results -
Old page1 ranked 1st on Apr 23rd.
Old page1 ranked 100ish on 24th
Old page1 ranked 6th on 25th.
old page1 ranked 8-10 on 25-27th
Old page1 ranks 100+ today
In my opinion, if it's not broken - don't fix it. It was alright for 5 years to rank in top1, I don't believe site just become bad overnight.
I guess we just have to wait until serps settle down..
