7 IPC is plenty for a revised bid, IMHO. Just need some punch to close Egypt on Germany 1.
Though, lately I’ve been getting sneaky and bidding 30 IPC to be Axis so I can work on KJF in “normal” games where my opponent is unaware I am going to hit him with it. A lot of fun! Had a few games given to me when my opponent sees a massive fleet emerge off the coast of S. America into the Pacific and his fleet is far away. :P
