I should clarify n correct my past comments re how the bid is used in tournaments; In tournaments; you can only buy units with the bid. You cannot buy bases or factories (right away), and you cant save money.
However, at Gencon/Origins/Smorey Swamp TN, you can put all the units in one square.  This apparently didn’t come up in the earlier tournament in 2016, but no-one there objected to putting the higher bids all in one square in 2017, which is not really a problem in most editions but it adds some choices when the bid is higher.
42.2 average bids 7-12 to Allies
G42 average bids 0 to either
Classic automatic bid of 9 to Axis
G40 no tourney bid that I know of but bids average 8-20 in leagueSince the bid is a house rule, you can apply it however you like.  The bid should be a game changer.  The bids that place a fighter into the German open or a sub (or 2) into Taranto change the game and change blowout battles into more equal contests.
That is interesting that in tournaments you are not allowed to save money.
Like I said earlier, the main reason I like to save most of the bid has to do with the fact that the UK will know where it needs to focus its resources much better at the start of its second round compared to round 1. Although I will admit a sub for the Med and fighter on Scotland is very good value and tough to beat.
